This may seem unkind, but they are the worst of the 4 Smiths tribs I've seen.
it's true, like another poster says, that you just go along for a drunken singalong, so i don't wanna seem like a purist/elitist but the singer is really poor, and he's fronting a just-about-average band.
Ironically, they seem to have a very good following (in Leeds last year, anyway), but i think they've been around longer than some of the others.
For the record, the others I've seen are:
The Smyths (excellent)
Sweet & Tender Hooligans (excellent)
Smiths Indeed (reasonable)
I know I'm a bit judgemental here, but, well, you did ask...
