Nigella Lawson is not welcome in America because of drug allegations - in discussing this news item Chris Evans (R2 Breakfast Show) named other celebrities who have been banned for the same reason including:

And tonight - a real treat: a repeat (on BBC4) of an excellent 2-part Arena documentary:
The Brian Epstein Story
Those early days of Brian and the band never cease to fascinate. And I expect some of the following programmes on the Sounds of the Sixties will include Beatle numbers too.  I'll have to "catch-up" with these later in the week.
