Sesame Street producer Aimee Blackton also shared a snap of Grohl playing guitar on set.
Sesame Street will begin airing its 50th anniversary season in February 2019. There’s been no word as to when we can expect the episode featuring Grohl, or what the episode will entail.
This isn’t the first time Grohl has featured in The Muppets universe. Back in 2011, he made a cameo in the feature-length film The Muppets – as a fill-in drummer for The Moopets cover band.
