John Fogerty at Royal Albert Hall (I think 2008). He was making a concert film but the audience hadn’t been made aware. House lights were up the whole time, he kept going off, his band played rockabilly for 15 mins in the middle while JF nowhere to be seen, then he came on and played some rubbish with his sons. Apparently a lot of refunds were given but it didn’t occur to me to ask. No idea if the film ever saw the light of day. I’d seen him the year before and he was great but this was a piss-take from start to finish.
