Went to see Mamma Mia last night with DD. Packed theatre, and it's the sort of show where everyone knows all of the songs.
Had the misfortune to sit directly in front of a group of about 5 women who seemed to think it was a karaoke or singalong performance. By the time we'd got to "Thank you for the Music" I was ready for strangling them lot of them. Few hard stares from me, DD and other people around us finally shut them up.
But AIBU to think that when you pay to see a professional cast, it's the cast you want to hear sing, not randomers?
(Apart from the show's finale though where everyone is up and belting out Waterloo)
