I usually tune into his show on a Sunday night when I get the chance, but for the last month they have been broadcasting repeats of his shows from 2009. There is no reason given for his absence so I assume he must be unwell and he is 86 now, hope he recovers soon if this is the case.
I think he's on holiday, I'm sure there was some announcement saying that they would broadcast some repeats until his return.
According to the Sunday Times it was announced last week, before another repeat, that he is currently recovering from two major operations in the last few months and hopes to return at some point.
Get well soon David.
He was very popular on Juke Box Jury. I had no idea he was still working.
