This is the bass-line that goes on during most of the song. G|---------------------------------------------------------------------------| D|---------------------------------------------------------------------------| A|--------------------3-0303-5-5-5-557-888-----------------------------------| E|-3-3-3-3-33-1-1-1-1----------------------8-858-----------------------------| An alternative version with different finger positions on the end: G|---------------------------------------------------------------------------| D|---------------------------------------------------------------------------| A|--------------------3-0303-5-5-5-557-888-3-0303----------------------------| E|-3-3-3-3-33-1-1-1-1--------------------------------------------------------| I haven't figured out the part that's played during the "solo" during the live-performance on Jimmy Kimmel. The bass follows the electric guitar and ukelele instead of doing something that resembles the main line like the album-version. So if anyone has a clue about that one please comment.
