Putting the Damage On: "Putting The Damage On" is a ballad by American singer and songwriter Tori Amos, and is featured as the 17th track on her 1996 album, "Boys For Pele".

In the song, Amos is accompanied by her own piano playing, and by the Black Dyke Band (which decades earlier had provided the brass band segments in The Beatles song Yellow Submarine).
