Celebrity guessing

Can anyone guess who these people are? I reckon they are from the 70s/80s era, and probably from the UK.

A CHART STAR: Good-looking and a very big international name. Famous for a string of top 10 hits including teen ballads. Huge young following. Cultivates a squeaky-clean image. This man has also recently found success in another branch of showbiz.

· A POP IDOL: Member of world-famous pop band whose bizarre clothes have been copied by diehard young fans. Figured on thousands of posters on teenagers’ bedroom walls.

· A TV PRESENTER: A huge celebrity. Presents family shows and is a regular at telly charity events. He was sacked from a charity in Ethiopia. A housewives’ favourite, he has carried out voluntary work.

· A PEER: A married earl who served in the House of Lords for more than 20 years as a Lib-Dem. He had an unblemished record of public service and had completed a good deal of work with children’s charities. The peer, who ran a jazz shop in his youth, was a former pupil at the Scottish public school Gordonstoun, where Prince Charles was once a boarder.

· TWO DJs: One, a Radio 1 legend. The second DJ has been an influential record industry figure.

Bumping this because I have no clue and would like to find out.

Well?

Donny Osmond is my best guess:(

I don’t know for sure, but I found the following guesses online:
A PEER - Tim Beaumont, Lord of Bintley
TWO DJs - Chris Denning *I understand this one is confirmed?

OK I’m pretty sure one of them is Pee Wee Herman because I think he’s been named. I don’t know whether he’s the CHART STAR or the POP IDOL though.

And yes, Chris Denning has been named. Confirmed I don’t know, because it hasn’t gone to trial, the extradition bid failed.

Tim Beaumont I don’t know, but he’s Green not Lib-Dem. Is he actually an Earl?

I also found David Christie for “sacked from a charity in Ethiopia.” But I’ve never heard of him before, as a TV presenter or anything else, let alone a “housewives’ favourite.”
