We already know that Dave Grohl is the Nicest Man in Rock.

He's also a pretty damned talented musician, to boot - as he proves daily as the frontman of Foo Fighters.

But if you were looking for a reason to possibly love him even more, you've found it below.

Grohl's appearance on 'Sesame Street' was teased last year when images of him on set were revealed. Now, the full performance of the rocky 'Here We Go Song' with Big Bird and Elmo has been unveiled.

The new season of the children's show will air in the US on November 16th, and the reason for Grohl's involvement is that it's celebrating its 50th birthday this year.

To say that he embraces the concept wholeheartedly is an understatement. What a guy.
