This is an acoustic singalong group for folks who like to play and sing 60s and 70s rock, folk-rock, country-rock, and other styles. Not a jam. More of a circle where one person at a time plays and sings a well-known song and others are free to add vocal harmony, lead instrument parts, percussion, or whatever. Sometimes there's a theme for each meeting, such as Beatles songs, one-hit-wonders, songs about cars, Motown songs, songs about surfing, political songs, or whatever. Meets in Vallejo, off 780, might sometimes meet in Berkeley or Walnut Creek.
