Olivia Newton-John At The BBC

BBC2, 10.15pm

The first programme in an evening of tributes to the muchloved star (below), who passed away in August, features clips of her appearances on music and chat shows from the BBC archive. It's followed at 11.15pm by a rare chance to see the 1980 roller-skating fantasy movie Xanadu, which falls into the ‘so bad it's good' category, before the 1977 TV special Only Olivia rounds off the night at 12.50am. ★★★★☆
