All About That Bass singer Meghan Trainor will be heading over to the UK to perform live, and Josh Groban will also be singing one of his hits. West End musical The Commitments are also treating us to a showcase of some of their numbers.
Comedy comes from Lee Nelson and Rod Woodward, and violinist and conductor Andre Rieu and his Johann Strauss Orchestra are also performing. Alexander gets in on the fun by joining The Commitments and collaborating with Josh Groban for a one-off duet too.
