For most of the 90s and mid-2000s, Swann split his time between Los Angeles and Nashville, writing songs for the biggest names in country and pop music. He became very active with the Songwriter's Guild of America, initially by holding songwriting workshops for the organization's non-profit foundation, and ultimately being named to the organization's board of directors. Through the guild, he became friends and a collaborator with legendary songwriters such as Jack Segal, Bobby Troop, Vic Mizzy, Donald Kahn, Al Kasha and Ray Evans.
