From Shine a Light, the Rolling Stones live with Jack White. Loving Cup is one of my favorite Stones tracks and this is a nice version which seems to gain added Stoniness from the non-Stones member. I don't know how White does this - older musicians seem to love having him around, and he seems to add something special to them. He's a musician's musician who's popular with the crowd as well, I guess.

In this case, a lot of the thrill is seeing how happy he is to play with the Stones. Getting a smile from Jagger, a signal to go into the coda from Keef, it makes his night and in turn he makes mine. Dig the accents - Mick sings the first line, Jack takes the second in perfect Jaggerese, which seems to set off some sort of accent-one-upmanship in Jagger. I suppose it doesn't take much with him, but it was odd to hear a little bit of Boston in amongst all that...that...that whatever-it-is accent he sings this in.
If they'd sung the whole of Exile, I'd have been an even happier camper.
