Brian May did not play with 'The Others', but he did attend the same grammar school as the band.
He did play with one of 'The Others' - Pete 'Wooly' Hammerton, and yes, a recording does exist - but it is very poor quality.
Ad Hoc Trio: Unreleased Live Shepperton Rowing Club Winter 1965
Not a 1984 performance, but rather an ad-hoc trio comprising:
Brian May - Bass guitar/ vocals,
Pete 'Woolly' Hammerton ('The Others') - Guitar/ vocals,
Richard Thompson (1984) - drums.
Poorest of all 1984/Brian May recordings, Brian plays bass guitar only (and not the famous 'Red Special), but cannot clearly be heard. Valued £1,000, Christies April 1996.
