Last night, Jimmy Fallon added Virgin FreeFest’s killer noon actThe Temper Trap to his long list of buzzworthy musical guests. The Australian rockers of course played one of the two catchy singles that everyone knows them for — this time around it was “Fader” — and did so well, but however good the music was, there are two things that overshadowed the song that you’ll want to look out for. 1.) Singer Dougy Mandagi’s awesome mahogany-red shoes and 2.) bassist Jonathon Aherne’s elbow dancing. That is all.
