I certainly didn't watch it & I couldn't believe my eyes when I saw it listed.....unbelievable for xmas weekend viewing but would anyone want to watch it at anytime?!
Surely by definition, someone who is no longer popular as an entertainer is no longer of sustained interest in a 'What happened to ...' set-up.
