AGNETHA'S BUM-RUSHES BOOKED APPEARANCES: There's three artists who you'd be surprised to see back doing a promotional tour - four, if you count Richey Edwards. Kevin Shields on Live At Johnny's? Unlikely. Kate Bush singing over the closing credits on This Morning? We'd be surprised. Agnetha Falkstog on Parkinson? Actually, that nearly happened - the one out of Abba who my Dad had a thing for had been booked to do the Barnsley misanthrope's chat show as part of the promotional tour for the new album My Colouring Book. But only nearly, as Agnetha has pulled all the promo she was going to do, much to the annoyance of Warners. It also looks like that her decision to suspend all plans will knock the 30th anniversary Abba reunion on the head. Maybe in 2014, then.
