throughout 1968 and 69 the bonzos also found time to record a large number of radio sessions for bbc radio 1's top gear programme hosted by john peel, where they took the opportunity to try out more experimental works such as the musical suite "sofahead" and an extended concept piece co-written with arthur brown titled "the brain opera" (which aside from brief excerpts released in 1971 by arthur brown's kingdom come remained unrealised). these regular appearances on peel's show kick-started vivian stanshall's long and fruitful association with peel and bbc radio, which continued until stanshall's death in 1995.
