"Sailcat was a short-lived American rock and roll band. They were a one-hit wonder who scored a hit single in the summer of 1972 with the song "Motorcycle Mama".

The cover art was drawn by comics illustrator Jack Davis and featured a series of motorcycle related drawings for each song on the album. The concept album's songs loosely tell the story of a motorcycle vagrant, who apparently steals for a living, meeting a woman and settling down to start a family. However, he apparently keeps some of his selfish behaviours as the last drawing shows him reclining on his porch while his wife hangs the laundry and his child hoes the garden.
