It is very likely Pete Townshend played bass on it. He played bass for Thunderclap Newman another Track Records/ Action Managment project from the same era. He used the pseudonym "Bijou Drains" with Newman. Gunther Toody said:
I can't tell you how much Arthur Brown and that first album mean to me...THE CRAZY WORLD OF ARTHUR BROWN was one of the first 10 albums I ever bought as a kid. There was an article with great color pics of Arthur live in EYE magazine and the cool colorful cover of the LP and that was all my adolescent mind needed to invest my saved lunch money in what has to be the most psychedelic 60's rock record with no guitar on it. Vincent Crane was amazing and the weird strings and horns that pop in occasionally are really cool. Anybody else hear the rumor that Pete Townsend played the bass in a last minute time crunch? And does anybody else think that Deep Purple's Ian Gillian kinda ripped off Arthur's distintive screamin' technique? Which is rarer...the Atlantic issues or the Track issues?
