Old friends Liza Minnelli and Graham Norton have a lot of catching up to do.

She's been on his show numerous times before but the last time was on V Graham Norton way back in 2003 when she came with her then husband David Gest. A lot of water has passed under that particular bridge since then...

With a new CD to promote, Liza kicks off a tour at the Royal Albert Hall at the end of this month, with dates in Europe and Las Vegas - and she'll be singing tonight.

Joining her on the sofa is Shameless actor turned Hollywood star James McAvoy, who'll have all the goss from the new X Men movie in which he plays the young Professor X, and Lead Balloon star Jack Dee completes the line up.

When Jack Dee is only the third most interesting person on the bill, you know you're in for a good show.

TV is full of comedy quiz shows, but the sheer silliness of Shooting Stars separates it from the bullying boys' clubs its peers regularly descend into. The lack of ego is refreshing, Vic and Bob are always only too willing to shame themselves to service a gag - as seen in Vic's wardrobe malfunction tonight when he dances. Angelos Epithemiou's hard work as the replacement for George Dawes pays off with some great moments, including a killer off-the-cuff insult at the expense of David Gest.

This could possibly be the most deranged variety show you'll ever see, the only place on earth where you can watch Christopher Biggins pretending to be Boris Johnson, and Jerry Hall impersonating Katie Price. If that doesn't draw you in, how about Joe Pasquale as Lady Ga-Ga? Or Ulrika Jonsson as David Beckham? No? Surely Vanessa Feltz masquerading as James May is irresistible. As is Eamonn Holmes as Elvis Presley. And David Gest as Elton John. Les Dennis as Gary Barlow... The list goes on, and just gets odder. The All Star Impressions Show could be completely awful or it could be enjoyably barmy. It certainly has a very good pedigree, being co-produced by Steve Coogan's and Vic Reeves and Bob Mortimer's production companies. And it has a certain surreal gloss that could be quite winning. Harry Hill will make a guest appearance, though we don't know whether he will reprise the Morrissey impression that won him Celebrity Stars in Their Eyes all those years ago.

If you thought that George Galloway pretending to be a cat on Big Brother was bizarre, ITV1 has cranked up the weird-o-meter with this programme, which must have been conceived after a heavy-drinking session among channel executives. It involves one famous person doing an impression of another - a concept that could result in an awful abyss of ineptitude and sycophancy, with Stephen Mullhern's commentary digging it into an even deeper hole. But read this line-up and defy yourself not to be horribly compelled to watch. Joe Pasquale as Lady Gaga, David Gest as Sir Tom Jones, Jerry Hall as Katie Price, Christopher Biggins as Boris Johnson, Vanessa Feltz as James May, Tim Healy and Paul Daniels as an elderly Ant and Dec. Pardon?
