When has there been a game in overtime during the NHL Stanley Cup final in game 7?

I have a bet with someone, and I'm almost certain there has been a game in overtime during game 7 of the Stanley Cup final. He claims there has not been. Unfortunately, I can't seem to find any info on this on google. Anyone know of such a game in overtime? Link please? Thanks!|||Yes it's happened twice.
