Tonight is the night! The first of two 50th anniversary proms celebrating the music of Doctor Who takes place tonight at London's Royal Albert Hall. The musical spectacle will get a television broadcast at an as-yet unspecified point in the future, but you can catch it live on BBC Radio 3 tonight at 7:30pm UK time. It's estimated to end at 9.45pm.

Listen live online here.

Listeners (and the lucky audience members) will be treated to a variety of music, consisting of Murray Gold's compositions from the series itself, a medley of music from 20th century Doctor Who and other atmospheric classical works from Bizet, Debussy and Bach. Conducted by Ben Foster, the music will be performed live by the BBC National Orchestra of Wales and the London Philharmonic Choir.

And let's not forget, Murray Gold's Song for Fifty's première.

But could there be more surprises in store? SFCrowsNest reports that the actor playing the Twelfth Doctor could be revealed live on-stage:

The fantasy and science fiction author Stephen Hunt is reporting that at last night’s rehearsals for the Doctor Who-themed proms at the Albert Hall, the staff gathered there were briefed on a section of the proms where the identity of the new Doctor will either be revealed, or they will actually walk out live on stage tonight.

One thing is certain - it's going to be a show to remember... and it happens all over again for the second prom tomorrow!
