The whole song is just a varied strumming pattern of the same 4 open chords
C,A,E,F

C       A              E               F
Back to Santa Barbara, where the people know my name
C       A           E                    F
Down in Isla Vista, where the Freebirds' open late
C      A                E                   F
On DP, life's so sweet, everybody livin' on easy street
C                   A             E                             F
We're goin' back to Santa Barbara, where the people, the people know my name
