The Doubleclicks are a self-proclaimed "Nerdy-folk-singer-duo" from Portland, Oregon. Yesterday they posted a new song called Agent Coulson.
Last night in Marvel's Agents of SHIELD, Agent Coulson told Professor Elliot Randolph that he would love the Pacific North West and that they have a great Philharmonic.
And of course there was the conversation between Coulson and Pepper Potts about the cellist he had been seeing and how she was moving to Portland…
One of the Doubleclicks plays the cello… coincidence?
