Temporary drummer, Tony Bird, with the band for at least this gig as a replacement for Billy Bent/Sparkle, whose 21st birthday it was today, but he was still hospitalised (see details below):
Western Daily Press, Thursday July 29, 1971:
"Billy Bent, Stackridge's drummer, will spend his 21st birthday today in an isolation ward in Cleethorpes, Lincolnshire, where he was taken with a mystery bug last Friday, during Stackridge's current tour. The band has had to cancel a number of bookings. Billy should be out of hospital on Monday. Meanwhile Jason Lick drummer Tony Bird will be sitting in for him."
