Idea for a television show: "Later With Jools Holland And Simon Cowell"

Basically the concept would be that the suave boogie-piano enthusiast and bandleader would attract an eclectic collection of international megastars, up-and-coming trendsetters and forgotten giants of yesteryear to an intimate, club-like studio setting, and then Simon Cowell would give a frank assessment of the often wildly variable quality of their performances.

If Cowell is too expensive these days then Gordon Ramsay, or Jeremy Paxman - it is not as if one needs a musical genius to point out that Adele often sings flat, or that R Kelly is pretty much a karaoke act these days.
