ABBA tributes go head to head on Friday, October 29. At Cheltenham Town Hall, Mamma Mia, the Thank You for the Music 30th Anniversary Tour, is coming to raise the roof. The concert show (not to be confused with the West End musical) pays tribute to both Abba and The Bee Gees and features a Motown spectacular. Meanwhile, the same night, the satin suits are also out at Worcester's Huntingdon Hall where Waterloo The Show, by Abba UK, will provide a fix for city fans.
