I'm looking for the name of the song and/or artist that plays during the episode when Ben finds the Charlie Chaplin movie reel and he and Felicity are watching it on the roof. I'm looking for the version that plays on the DVD.

Not sure if it's what you want, but try "born yesterday" by mike schmid.
