The episode of Sunday Night at the Palladium hosted by Xander was repeated on 19th June. Apologies - this kind of sneaked up on me, so I didn't know about it in advance and couldn't let you know. Luckily. however, it's available to view online till 17th July.
Xander's guests are singers Josh Groban and Meghan Trainor, the cast of The Commitments, violinist Andre Rieu and US dance crew AAC Boys. It was an enjoyable show. Definitely recommended.
