Nicky Chinn and Mike Chapman's "Dynamite" was originally written for the biggest of their early-'70s hit bands, the Sweet. When they rejected it, the song passed to Hello, a new group then seeking their first hit. A raw, raucous version of the song was recorded, but before Hello could release it, Chinn/Chapman took it back and handed it, instead, to Mud. Hello's version remained unissued for the next 25 years; Mud's became their third U.K. hit in a row, and the first -- all concerned agree -- to truly encapsulate the band's magic.
Built around a thundering beat and an unabashed party atmosphere, "Dynamite" was tailor-made for the kind of high-kicking, fist-waving, flared-trouser-wearing dances which Mud's live and TV persona already delighted in. Even more importantly, however, Chapman recalled "that was when I discovered that Les Gray could sing like Elvis. Once I discovered what he could do, it was like a red rag to a bull. From thereon, Nicky and I were only concerned with writing songs that he could sing sounding like Elvis Presley."
