There's a brief but nice biography at allmusic.com:

b. 23 March 1934, Manchester, England. Although known for his humorous material, Wootton has also written more serious songs. Having started out in revue sketches at university, he then took up the guitar and started singing at the Heritage Folk Club at Oxford. This was followed by a residency at the Court House Folk Club in Cornwall. Moving to Brighton in 1965, Wootton began playing the local folk clubs, and writing songs with Allan Taylor. He contributed the lyrics to five tracks on Taylor’s debut, Sometimes, in 1971. Wootton subsequently plunged into a full-time career of singing and writing, with a number of artists covering his songs. A breakthrough of sorts came when he co-wrote, with Fred Wedlock, ‘Joggers Song’, the b-side of ‘The Oldest Swinger In Town’. This at least pushed his name forward to a wider audience. Wootton also wrote songs weekly for Wedlock when the latter appeared regularly on the Noel Edmonds Show for UK television. He has also contributed songs for BBC Radio’s satirical series, Week Ending. Wootton now plays only occasionally, but his songs are much covered and imitated.

May he rest in peace.
