HW: The cwazy world of Arthur Brown

[Bolts of Ungodly Vision]

I was looking of the aforementioned artist when I stumbled upon the following:

Brown continued to tour and record throughout the Seventies, appearing
briefly in Tommy, and
turning in guest studio performances with Cat Stevens, Alan Parsons, and
Hawkwind.

What did track/LP did he guest spot for Hawkwind? A rather interesting
combination it is
