It was written specifically for George Harrison to sing at a time when he lacked the confidence to compose his own material. Years later, McCartney described it as a "formula song", and Lennon said, "I would never have sung it myself."
Structurally, it features hectic Bo Diddley rhythm and busy banjo style guitar playing in juxtaposition with Harrison's vocal. Its composers give it an unpredictable choice of chord (augmenting the B7th on "I'm happy just to dance with you") right at the crux of its title, jarring the chorus. The song is also unique in that it begins not with a verse or chorus but with the last four bars of the bridge.
