"good" is in the ears of the listener, or not. But being as Paul Carrack has been the voice of Ace (How Long) and Mike & The Mechanics (Silent Running, Living Years, etc) I'd have said he would be well worth the ticket price.
.........as well as also being the singer with Squeeze(they had a big hit in the USA with tempted, Paul on lead vocals) for a little while during his career. I've seen him once and he is well worth the entrance fee. You'll have a great time.
