The Rabbit Rock Band

When The Rabbit Rock Band enters the battlefield, you may correctly sing the first verse
of lyrics to the song 'Back in Black'. If you do, creatures you control get +1+0 and gain lifelink
until end of turn.
Back in black! I Hit the sack! I've been too long! I'm
glad to be back! Yes I'm let loose! From the noose!
That's kept me hanging about! I keep looking at the
sky! Cause' it's getting me high! Forget the hearse
cause' I'll never die!
