Joe Johnson winning the world championship was the biggest shock this great event had witnessed up to that date but, make no mistake, he was a very good player but one whose achievements had never quite matched his talent - until then.

One of the best amateurs of his time, Joe was National Under-19 champion in 1971 and three times Yorkshire champion. He was runner-up to Terry Griffiths in the English Amateur championship of 1978 and, with Terry being a Welshman that qualified him as England’s representative in that year’s World Amateur in Malta. He gave a very good account of himself reaching the final where Cliff Wilson proved too good for him. That prompted him to turn professional in 1979.

Joe got off to a slow start as a professional, never getting beyond the qualifying stages of his first four world championships. A quarter-final in the 1982 Professional Players Tournament earned him his first ranking points and that season he reached the Crucible stage of the Embassy for the first time but lost his opening match. When he again lost in the first round of the Masters at Wembley people started to say that he could not perform in front of the TV cameras. It was not until the 1985 Mercantile Credit Classic that he won his first televised march. As an amateur however he held the world record break of 140; and that was televised! In the meantime, the 1983 Professional Players Tournament provided him with his first ranking final. 1-6 down to Tony Knowles at one stage, he fought back and only lost in the decider 9-8. Needless to say, this event was not televised. When he finally laid the TV ghost in that 1985 Mercantile Credit event he went on to reach the semi-final and ended that year in the top 16 - just.

The 1985/86 season got off to a modest start with just two quarter-finals and he arrived at the Crucible in April as a 150-1 outsider still looking for his first match win at that venue. In fact he had still not earned a single ranking point from the world championship in six attempts. This time, however, he got off to a good start with a 10-3 beating of Dave Martin and he had finally got that first win under his belt. Mike Hallett was his second round victim and then he edged past Terry Griffiths by the narrowest of margins, 13-12. He saw off Tony Knowles in the semis before facing Steve Davis, determined to regain the title he had lost to Dennis Taylor. Joe proved up to the task and ran out the winner 18-12. Joe was champion of the world.

Winning the world title seemed to have an adverse effect on his form and he had a poor season in 1986/87 not getting beyond the last 16 of any ranking event and again was given no hope of retaining his world title. In the event he surprised everyone and reached the final again. This time however, Steve Davis got his revenge by 18-14. This did however prove to Joe, as much as to everyone else, that he was good enough to win tournaments and he started the 1987/88 season by taking the Scottish Masters title. He followed this with a UK semi-final and got to the last four of the B & H Masters.

His second world final had taken him to fifth in the rankings but it proved to be down hill from then on. His form slumped and to add to his troubles he developed heart problems. By the end of the 1989/90 season, although he picked up the non-ranking European Grand Prix title, he had dropped out of the top 16, never to return. His eyesight was also giving him problems and he took a while to come to terms with playing in glasses. He did get back to the scene of his greatest triumph, the Crucible, in 1991 but did not get beyond the first round and since then his best performances have been a couple of quarter-finals in ranking events. The last few seasons have found Joe languishing in the mid fifties in the rankings but he continues to perform reasonably well and has not, so far, been in danger of losing his place on the tour. During the 2000/01 season however he only won three matches and his ranking dropped to an all-time low of 73, and in 2001/02 things were no better. Even though his ranking dropped to 90^th, he did do just enough to remain on the tour for yet another season and the story was the same during the next campaign. He had only won one match up to the Embassy qualifying but won three rounds in that event which proved to be just enough to keep him on the tour yet again.

He began the 2003/04 season with a bad injury which kept him off the table for nearly the whole season. He managed to recover enough to make token appearances in the final two events but failed to achieve a victory. Certain to drop off the Main Tour at the end of that season, he decided to retire from the game he had graced for 25 years as a professional.

In recent years he has devoted more of his time to encouraging young players, something with which he has become increasingly involved. He has also been doing some television commentary.
