With thanks to Ro for finding this gem - here's a 2008 US interview with Sir Tim Rice, in which he briefly discusses ADWD and Lee (there are a couple of nice 'Joseph' clips):-

Interesting comment about Lee winning ADWD:-

"Lee Mead was ... pretty good and, um ... of course they didn't rig it, but they were able to show him off in ways that might eliminate any possibility that anyone else would get it ..."

I remember that interview, thanks Jo and Ro. It's part of a series that's on public tv here in NYC, they have a website as well:

Tim Rice is so charming!
