If Paul won't play Mull in the USA because Girl School was the single instead, then he should play Girl School at every US gig.
Girls' School would be a great song to hear live! Maybe it wasn't fair of me to imply that he doesn't play Mull in the States because he's bitter that the record company pushed Girls' School instead of Mull, which possibly cost him another number 1 single and a lot of money as a result. While that is possibly true maybe he simply doesn't play it because he seeks to please his audience and since it wasn't a hit in the States he doesn't feel that it would get as positive a reception as a song that was a hit? Girls' School peaked at 33 or 34 or something like that so I guess that would be considered a deep cut from his catalogue if he thinks that the average concert goer is not familiar with many of his songs that weren't "hits" or Beatles songs. I would expect that any of the folks who are on this forum are likely die hard fans and would welcome an entire show of hidden gems and deep cuts, but he doesn't plan set lists for us. I do agree with whomever said that Mull is great for him to play now because it isn't one of his most challenging vocal performances and the spectacle of the pipe band joining him on stage is terrific for the show. I guess the other consideration is whether or not the place he is playing has a really good local pipe band that could join him on stage. (I'm would think that would be fairly easy in the American midwest and north east.)
