Gave it a 6. Not Rattle & Hum's best moment, but not a bad tune. Love Bono's vocals on this one, and who could forget BB?
It actually loses some steam because of The Edge. The Edge, let's face it, is not a bluesman. And his solo here is really out of place. They should have just let BB take all 3 solos.
By the way, I saw BB King live at Pier 6 in Baltimore two years ago and he played this tune with his band. A different arrangement, but it's nice to see that B.B. still appreciates the song from the Irish lads.
