The Ducks (formerly known as the Jeff Blackburn Band) were a short-lived hard rock supergroup formed in the summer of 1977 by singer-songwriter Jeff Blackburn, and consisted of musicians Bob Mosley (an original member of Moby Grape), Canadian singer-songwriter Neil Young, and Johnny Craviotto. The band played a series of impromptu bar gigs around the Santa Cruz area in 1977. Fans would often quack and blow duck callers before the band began playing.
