Description fits Muppet very well, but that he's a non-native well known in the town (though functioning out of West Yorks) is all I would add.

The mental picture of Tony Morris (who I also know) in Muppet's gear and doing his material is entertaining, to put it mildly. Tony has done a disc or two, but they don't resemble Muppet's act at all, nothing does. As far as I know Muppet has issued no recordings, though I would imagine that his local fans would love it if he did.
