They Might Be Giants 'Can't Keep Johnny Down' on 'Fallon'

Cult band performs song from their latest album 'Join Us'

They Might Be Giants swung by Late Night with Jimmy Fallon last night to play "Can't Keep Johnny Down," the opening number from Join Us, their first non-children's album since 2007. The song may not be written specifically for kids, but it's hardly "adult" in any lascivious or emotionally complicated sort of way. Like the vast majority of their material over the years, it's a charming, catchy tune with clever lyrics that can be appreciated by fans of all ages.
