This vid (not of the cricklewood gig Im afraid) is from a top notch copy of the commercially available (back then) Jettisoundz release...
Tree and me hung around for the main feature. Aparently half the band didnt turn up but luckily (!) one of the audience (who didnt appear to have a neck) knew the words to Skrewdrivers hit: "White Power" and they happily played that, like 4 or 5 times.
In a completely unrelated incident the pesky IRA bombed a road bridge just north of this pub , big bomb, much damage but it famously didnt even wake me up...... I got my hearing aid soon after.
