I saw FM in 1971/2 in Small Heath Park B'ham and they did the soundcheck behind a flimsy curtain on the next stage for 1/4 hour ruining the end of the previous act (who had played through a thunder storm to the very vocal delight of the soaking crowd). Then when the curtains opened they continued for another 1/4 hour tuning-up. Then they played the odd number with a load of undecipherable banter that the body language told me was pure egotism, as if we knew every pecadillo of theirs and we should not need to hear at the back. I walked away 1/3 into their spot. Albert Ross was disgusted at their arrogance too.
Nice tune shame about the demeanour.
Status Quo earlier on the bill - for all their repetitiveness - entertained me more.
