Strangers featuring Madeleine Peyroux, Steve Light, Jon Herington and Richard Hellis. Posted on YouTube two days ago.
We're suckers for "reality videos" like this. Apparently filmed just as it happened. Sound far from the best even if you click the HQ option. The video description says:
"At the Hostel in Soho. Madeleine Peyroux and John (sic) Herrington (sic) jammed with some of the guys from one of St Mungo's homeless hostels in London. This track was written by Steve Light."
