The final evening of the Glastonbury Music Festival played host to music duo Orbital, and they finished their performance with a rendition of an old favourite, the Doctor Who Theme.
However, a special unexpected guest appeared on stage to introduce the last song of the evening - none other than current Doctor Matt Smith! With a wibbly-wobbly timey-wimey arrival Matt roused the crowd and then joined the band for the performance.
Viewers in the UK can watch Matt's appearance and the performance on the BBC iplayer (from 1:50:22) for the next week.
A number of outlets have picked up on the story, including Gigwise, NME, Metro and the BBC.
And this article also mentions that Matt wasn't the only Doctor Who veteran to make a surprise appearance at this year's Glastonbury!
