They are closing their shows with "40" again. Christian references are constantly at play in their music. As a conservative, some of their left-wing politics grates on the ears, but as a Christian I love them and their music.
How about some Grateful Dead?
They say that Cain caught Abel,
Rollin loaded dice
Ace of spades behind his ear,
And him not thinking twice.
Oh wait, that's Old Testament. Nevermind.
That's a borderline-ecstatic experience live. Similar to Peter Gabriel's closing with "Biko."
