Yes - he certainly did perform BAAB
I attended the RVP & had a truly enjoyable time with Deb, Lou & Caryl. Meat was on towards the end of the 1st half of the show. As has already been said the stage was set up in the style of the 'dead-ringer' video. Meat performed BAAB first followed by DR with Jamelia. I thought that the pairing of Jamelia & Meat was great & they both got into character. Whilst singing Meat was prowling around the stage & got up on top of the 'bar' etc, which was fun as some of the other performers just stood relatively still by their microphones at the front of the stage.
It was a wonderful experience to see Meat finally performing at the RVP after all these years
I also enjoyed Rod Stewart & Take That were ok

But some acts, such as Ken Dodd, were IMO awful!
Unfortunately, I didn't get near Meat, but Lou was able to get an autograph when he was leaving the Coliseum.
I'm so pleased that Meat was able to perform at the RVP - it was great promotion

& I'm sure that Prince Charlie really enjoyed Meat's contribution to the show
