Season's Greetings From 'The Flash' Stars Tom Cavanagh And Carlos Valdes

By George Fox — @GeorgeJFox

It's become a holiday tradition for fans of "The Flash" and this year's installment is here! Tom Cavanagh and Carlos Valdes pick up their invisible instruments and after a little warm up perform a medley of "We With You A Merry Christmas" and "Jingle Bells".

Tom Cavanagh plays brilliant scientist Harrison Wells and super-villain Reverse-Flash and Carlos Valdes plays S.T.A.R. Labs engineer Cisco Ramon and superhero alter ego Vibe. Please Tweet me if I got any of that wrong.

Danielle Panabaker who plays Caitlin Snow and Killer Frost makes an appearance as the camera pans over to see her mildly-amused reaction.

Here are their 2014 and 2015 Season's Greetings performances.
