Bollywood ending?

Is this something that's becoming more popular? I just saw the end of Jersey Boys and it was the same thing--all singing and dancing. It made a bit more sense in that film, but I never thought I'd see Marty and Jeannie boogieing in the streets.

I wondered if it meant the show was ending--which it is, apparently.

I don't know, tough to end a show right, but I figured something less joyful than this.

Whatev's. Said to see it go. Guess I just expected more of a bang.
