The Swinging Blue Jeans are a four-piece 60s British merseybeat band, best known for their proto-rave-up hit single "Hippy Hippy Shake" (also known as "The Hippy Hippy Shake"). Intriguingly, while the song sounds rather Beatles-clone like, the Beatles did in fact do a cover version of this song for the BBC. The Swinging Blue Jeans had a spell of moderate success, breaking into the U.S. with the aforementioned hit but also charting again and again in the U.
