How many encores does your favorite band play live?

My favorite band, the Grateful Dead, would usually play one encore. Two, if you were lucky, back-to-back (and usually short tunes.) Well, I’m listening to a bootleg from 1978 when they played three, and one of them was an epic/long song. The crowd went wild, and it’s exhilarating to listen to.

However, I’ve been to shows (most recently selling t-shirts at a Celtic Woman concert) and the bands would just keep going off-stage, returning and repeat once or twice. It was almost like a third-set; the crowd went wild Well, as wild as a Celtic Woman audience can go.

So, how many encores for your favorite band?
