It's not so much the songs that Show of Hands sing, they perform them like wannabee pop stars

If they did want to be pop stars, I'm sure they could and would have achieved that by now - they have more than enough talent to do that if they want to. I don't see what's wrong with putting on an entertaining and professional show, whether we're talking about pop, folk or any other genre. Phil and Steve (and indeed Miranda) still play in 'proper' folk clubs as well as 'arts centre' or theatre venues, sometimes as solo artists, and sometimes with other bands. If you met them (as I have) you would realise they are as down to earth and friendly as most other folk performers I've met.

They are not trying to become pop stars IMO, just to provide what their fans want and make a living in the process. Can you blame them for wanting to do something different from time to time, after the best part of 20 years? They don't want to stand still in a 1970s timewarp.
