NHL hockey legends are in Calgary for a star-studded birthday party Friday.

Mr. Hockey himself, Gordie Howe, is celebrating his 85th birthday and kicking off a weekend-long tournament to raise funds for the Alzheimer Society of Alberta and Northwest Territories.

NHL superstars Alex Devecchio, Guy Lafleur, Frank Mahovlich and Garry Unger will all be present for the kick off of the pro-am face off for Alzheimer’s.

The local fundraiser gives amateur hockey players a chance to play alongside hockey greats, and raise money for the cause.
