On Drums: Stewart Copeland!
Friday, BBC4, 9pm
Stewart Copeland, formerly of The Police, was once ranked at No 10 in Rolling Stone magazine's list of the 100 greatest drummers of all time. So he's definitely qualified to host this programme, which explores the drums as the founding instrument of popular modern music. Along the way, Copeland plays with some of the most inspiring drummers of the past 50 years, including John Densmore of The Doors, Chad Smith of Red Hot Chilli Peppers, Prince's musical director Sheila E, New Order's Stephen Morris, and the Foo Fighters' Taylor Hawkins. He also goes dancing in New Orleans, builds his own bass drum pedal and checks out hot new bands on Santa Monica beach.
QI
Friday, BBC2, 10pm
Now in its 16th year, QI shows no signs of growing old yet and is still as wonderfully silly yet informative as ever. It's even survived a change of host: Stephen Fry occasionally seemed rather jaded towards the end of his tenure, but Sandi Toksvig has given the show renewed energy. Following a short break, the programme is back with the remaining episodes of the "P" series as Jimmy Carr, Lee Mack, Alice Levine and, of course, Alan Davies, consider Pain and Punishment.

Through the Keyhole
Saturday, UTV, 9.30pm
Let's face it: many of us love to see how the other half lives – especially if that other half is a celebrity. For more than 30 years, Through the Keyhole has played the nosey neighbour while underoing various revamps. The latest series is hosted by Keith Lemon, who is a far cry from original presenter David Frost. Tonight Danny Dyer, Sally Phillips and Chris Kamara attempt to identify who are the owners of three mystery homes via their furniture, decor and personal items.
World's Weirdest Homes
Sunday, Channel 4, 7pm
From a kaleidoscopic house fit for a Canadian Batman, to a Mexican house floating on 160,000 plastic bottles and a tiny cottage in Scotland that's like something from The Hobbit, Charlie Luxton reveals more fabulously bizarre homes. He meets the eccentric owners too, including a Middlesbrough carpenter who keeps building houses that get washed away by hurricanes, a Russian clown who likes to row his bed down a river, and a Cuban artist who started a revolution in his own neighbourhood.

The character, created by novelist Ann Cleeves, is once again played by Brenda Blethyn. The first of her four cases, entitled Blind Spot, sees her investigate the murder of a trainee forensic psychologist whose body was found on a landfill site.
