One from the 'sort of a festival' file now. Embrace (again), Sugababes, Lionel Richie, Ronan Keating, Pink, Barry and Robin Gibb, and what BBC Online refer to as "Scotland's Annie Lennox" (oh, that Annie Lennox) will all appear at the Princes Trust 30th birthday party at the Tower Of London on 20 May, which is kind of replacing the old Party In The Park event this year.
The televised extravaganza will also feature an interview with Prince Charles and his sons William and Harry, conducted by Ant and Dec. And if that hasn't put you off - Ben Elton, Patrick Kielty and Kate Thornton are all hosting. Highlights from the show will be aired the same day on ITV. Let's hope the BBC put something good on that day.
