Honestly don't remember the 1990 gig, to busy with a young family maybe.
Saw Mecca with wings at the Empire 1973, think it was the Venus and Mars tour. They overran their allotted time and a guy from back stage came on and told them to stop playing, when they didn't he literally pulled the plug
Saw him again when he played the Cavern in December 1999. We were at the live feed at Chavasse park, at least I think it was there
Also attended the 2008 Anfield gig.
