help! can't find a show i saw an advert for

I'm hoping somebody else saw this commercial and has a better memory for it than I do...

There was something advertised the other day that was a series of single-episode shows by the UK's top comedic talents. The first one was supposed to be by Martin Freeman, but I can't remember who else was involved.

My problem is that I don't remember what channel I was watching (I think it might have been BBC3, but I can't find anything on the BBC website), and I don't remember when it was supposed to air (I thought it was starting last Friday, but couldn't find anything in the listings).

Does this sound familiar to anyone?

Thanks.

It's Comedy Showcase C4 Friday 10pm

Oh, that sounds interesting!  Thanks for the heads-up.

It's Comedy Showcase C4 Friday 10pm

That was it.  It was on after Ugly Betty, which I didn't see till Sat and was upset that I missed the fist show from Comedy Showcase. (Saw the advert and stopped while fast forwarding to see what it was)
