Sorry, I'm not grading on an age curve. The performance was bad. Half because of the horrible audio production. Half because the guy can't sing that way anymore. Lots of older rockers have had to adapt their performances and songs to their changed vocal and/or playing abilities. Some manage and others don't. I'd much rather have the memory and recordings of The Who live on relatively unvarnished without these guys turning in half good performances for a quick buck.
Stage and light production was top notch though.
