By 1976, the only original members remaining were Thijs van Leer and bassist Bert Ruiter. Thijs then put together a new line-up of the band, in preparation for a UK tour. He recruited Philip Catherine, an established and respected jazz fusion guitarist and songwriter. The band was then completed with the addition of David Kemper on drums, a veteran of many Los Angeles sessions who would later accompany Jerry Garcia and Bob Dylan on tour.

Recorded in London on 21st March 1976 by the BBC, this concert includes new material as well as old stage favourites, House Of The King and Hocus Pocus.
