Try visiting the Goodby, Silverstein & Partners, San Francisco website (they created the ad for AT&T).
You should be able to write to them requesting a list of credits. Good luck.
: Does anyone know the name of the song played for the AT&T wireless commercial where a girl is in a business meeting and her boyfried comes to the door with signs apologizing to her? There are no lyrics during the part thats played, but the music is cool. If you know, please respond to this and if you have the time email me also. Thanks.
