Former Mega City Four singer Darren "Wiz" Brown died from a blood clot on the brain on December 6, 2006.
He was taken ill at a rehearsal earlier in the week and died Wednesday afternoon at St Georges Hospital, Tooting, South London.
Wiz, 44, was living and working in Farnborough, Hants. He had just finished writing material for an album for his current band Ipanema and returned from a successful tour in America.
With his guitarist brother Danny, bassist Gerry Bryant and drummer Chris Jones, the band released 6 studio albums between 1989 and 1996 and achieved success as a live touring band travelling the world.
