BUT WILL ARNOLD BE THERE, TOO?: Tony Blackburn's Indian Summer continues, with the news that he's to rejoin BBC Radio London (or BC RD LDN or whatever they call it) to do a soul show on Saturday lunchtimes. We've always liked that Tony has a musical hinterland, and regardless of the shit he pumped out on Radio One actually had a passion for music nevertheless, and it's kind of funny that soul music seems to have got a small boost in the London market as a side-effect of the first series of I'm A Celeb. And if it helps him pay the rent without the need to do any more of those demeaning ads for the Daily Express, so much the better. We're just not sure that we'd agreethat he's "probably the best known DJ in Britain" - surely that's Wogan?
