It's the film that television and music fans alike have been waiting 41 years to see - it's Maggie Smith starring in a music video to Rod Stewart's 1971 classic, Maggie Mae.
Now, we're not 100 per cent convinced that this Downton Abbey "best of Lady Violet" collection is an officially sanctioned Rod Stewart release - but it is quite a good watch...
So, with the prospect of Downton Abbey series three nothing more than a distant speck on the period drama horizon, for now, sit back, relax and indulge yourself with this blues-rock fancy-dress extravaganza.
