Since 1979, he has been a member of the British progressive rock band Camel, who, after a ten-year hiatus due to the ill health of bandleader Andrew Latimer, returned to active touring in 2013.

The title track of the first, "Denpasar Moon", became a hugely popular song in Indonesia in the mid-1990s and has been covered by over 50 Indonesian, Malaysian, Japanese and Filipino artists.

The band became part of London's growing Pub-Rock scene and briefly signed with Island Records but were dropped after differences with producer Muff Winwood.

In 1977, Bass was invited by American saxophonist and composer Jim Cuomo, who had occasionally played with Clancy, to participate in his musical Woe Babylon at the Edinburgh Festival.

The line-up at the time was Andrew Latimer (guitar, vocals), Andy Ward (drums) and keyboardists Kit Watkins (ex-Happy The Man) and Jan Schelhaas (ex-Caravan).

Returning to the UK in 1983 he took up a teaching post, played sessions and club and pub gigs with various line-ups until Andrew Latimer invited him to rejoin Camel for the 1984 "Stationary Traveller" tour.

[3] Between 1985 and 1991, the 3 Mustaphas 3 recorded four full albums and sundry singles and EPs and established a cult following for their live performances, touring in the USA, Europe, Japan and also in the then Eastern Bloc countries of East Germany, Hungary and Bulgaria.

The title cut from that record is played as pre-show music for the nighttime fireworks/water spectacular IllumiNations: Reflections of Earth at Epcot, located in Walt Disney World in Orlando, Florida.

At the same time, the 1990s saw a rejuvenated Camel back on the scene after a long period of inactivity due to a protracted legal dispute with previous management.
