I remember when I first watched the Concert for Bangladesh. I reckoned it probably didn’t get much more special than that. The Billy Preston That’s The Way God Planned It moment? Quite unbelievable. And then I remember finding this footage of Bob Dylan and George Harrison rehearsing If Not For You on the extras. I didn’t stop playing it for weeks. It’s the tentativeness that gets me, every time. And the bit where they laugh, of course. Too good.
