Answer by taking a quote from the following article:

Sir Ian Terence Botham, OBE (born 24 November 1955) is an English former cricketer and current cricket commentator. Widely regarded as one of the greatest all-rounders in cricket history, Botham represented England in both Test and One-Day International cricket. He played most of his first-class cricket for Somerset, and also for Worcestershire, Durham and Queensland. He was an aggressive right-handed batsman and, as a right arm fast-medium bowler, was noted for his swing bowling.

Mike Brearley announced his retirement from Test cricket after the Jubilee Test in Bombay and, somewhat surprisingly given his lack of captaincy experience, Botham was appointed to replace him as England's captain for the forthcoming home series against West Indies, who were at the time the world's outstanding team. Botham led England in twelve Tests in 1980 and 1981 but he was unsuccessful, the team achieving no wins, eight draws and four defeats under his leadership. In addition, his form suffered and was eventually dismissed from the post, although he did actually resign just before the selectors were about to fire him. In Botham's defence, nine of his matches as captain were against West Indies, who afterwards won twelve of their next thirteen Tests against England. The other three were all against Australia. In 1980, which was a wet summer, West Indies had the better of all five Test matches, although, with the rain constantly intervening, they were able to win only one of them. Botham had a poor season as a bowler and, in all first-class cricket, took just 40 wickets at the high average of 34.67 with a best return of only four for 38. He did better as a batsman, scoring 1,149 runs (the second time, after 1976, that he topped a thousand in a season) at 42.55. He completed two centuries and six other half-centuries. His highest score in the season was ultimately the highest of his career: 228 for Somerset against Gloucestershire at Taunton in May. He batted for just over three hours, hitting 27 fours and ten sixes. With Gloucestershire batting out time for a draw on the final day, Somerset used all eleven players as bowlers. Apart from an innings of 57 in the first Test, Botham contributed little to England in the series and that innings was the only time he reached 50 in all his twelve Tests as England captain. Somerset came close to retaining their JPL title in 1980 but had to be content with second place, only two points behind Warwickshire. They finished a credible fifth in the County Championship but were eliminated from both the Gillette and B&H Cups in the opening phase. Botham led England on the controversial tour of the West Indies from January to April 1981. The second Test, scheduled to be played at Bourda, was cancelled after the Guyanese government revoking the visa of Robin Jackman because of his playing and coaching links with South Africa. The other four Tests were played and West Indies won the series 2-0 but England were helped by rain in the two drawn matches. Botham took the most wickets for England, but Wisden said "his bowling never recovered the full rhythm of a year before". His batting, however, apart from one good LOI performance, "was found wanting in technique, concentration and eventually in confidence". In Wisden's view, Botham's loss of form "could be cited as eloquent evidence of the undesirability of saddling a fast bowler and vital all-rounder with the extra burden of captaincy".

Did he play at Somerset?
