England’s Newest Hitmakers
Side 2, Track 6
Keith steals the show on this cover of an R&B standard, both with his guitar and his hilariously nasal harmony vocal part. In the spoken middle section, Mick shows the beginnings of the vocal style that would end with the glorious self-parodying in "Miss You", with those "Puerto Rican girls just DAAAAAHHHHHNNN to meeechoo!"
UPDATE: I've since learned that those nasal background vocals come from Brian Jones, not Keith, who didn't sing on this album.
