I decided to give the Live in Tokyo album another listen today as it had been some time since I'd listened to it. I was really struck by this version of Wait for Sleep this time through. I'm not sure what it is exactly, but there's a really comfortable vibe to it. I think it has to do with the combination of JLB's singing, KM's playing, and the overall balance of the band.
I've gone back and relistened to it a few times now and it's just stuck in head now.
Thanks for letting me share.
