Def Leppard have a huge chip on their shoulder about being lumped in with the U.K. and U.S. hair-metal bands of the Eighties. To set the record straight, they've recorded this album of covers of songs by their real heroes: people like David Bowie, T.Rex and the Kinks, as well as lesser-known Seventies rockers such as Sweet and John Kongos. Happily, Yeah! is their most convincing album in fourteen years, which proves their point. Standout tracks include a straightforward cover of David Essex's ""Rock On"" and an amped-up take on the Faces' ""Stay With Me,"" in which Phil Collen seems to conjure Rod Stewart. The only real misstep is a flat rendition of Blondie's ""Hanging on the Telephone"" (coincidentally the only American group on the album). None of the arrangements veer far from the originals, but they don't need to — it's good enough to just hear the band having fun and to see where all the Hysteria came from.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
