SIMON GARFIELD's article on Abba ('Super Troupers', Review, 21 February), contained two elementary errors of fact. Bjorn Ulvaeus usually played guitar. Benny Andersson played keyboards. It was also Ulvaeus who was married to Agnetha Faltskog - however, he wasn't the one with the beard. That was Andersson again.
