All the songs in the 2000 musical The Witches Of Eastwick have lyrics by John Dempsey and music by Dana P. Rowe. This one, from the first act, is performed primarily by Sukie with some vocal interjections from Darryl. As might be discerned from its title, she is a woman who likes to talk.
"(What's So Funny 'Bout) Peace, Love, and Understanding" was written by Nick Lowe in 1974. The original version with his group Brinsley Schwarz was kind of somber, but Elvis Costello made it a classic with his 1978 uptempo take.
