I was looking for a clip of Teri Garr as part of the opening number in the '80's, riding a bi-plane singing something like "We're going-going to the O'ee's..." but no one seems to have been interested enough to post it...
Neil Young, "Philadelphia" Philadelphia -When Tom Hanks won the Oscar he seemed to revere that song over Springsteen's "Streets of Philadelphia". Hear the song, you understand why.
And recently "I See the Light" from Tangled because I was surrounded by a bunch of Chuck fans during the telecast completely aghast that Zachary Levi was a.) singing and b.) so very into it.
