"Doin' Time"(aka Summertime) by Sublime Tabbed by Mark D. [email protected] Key- X-muted string Written by Brad Nowell, Marshall Goddman, George Gerswhin, Ira Gershwin, Du Bose Heyward, and Dorothy Heyward. Well Brad doesn't use much guitar on this except for the break, but the xylophone intro and main riff sounds good if you use a clean electric guitar.This is the intro. Simple. Just repeat throughout the song. Gm C (let ring) E|-----------------| B|----3---5--------| G|----3---5--------| D|-5---------------| A|-----------------| E|-----------------|And then the break. ("Me and my girl...") Gm C6 E|--X-3-------X--3--X--5---| B|--X-3--X-3--X--3--X--5---| G|---------X--3------------| D|-------------------------| A|-------------------------| E|-------------------------| Very easy.
