Mark from London, EnglandThe Wurzels were known as Adge Cutler and The Wurzels in the 1960s when they recorded the song "Drink Up Thee Zyder". Adge was sadly killed in a car crash.
The three Wurzels recorded under their shortened name and had several hits (all parodies in the same style) in quick succession in the UK, this being the first and most successful, reaching number one. Note that, even though they all sang in exaggerated West Country accents, one of them was Scottish!
"(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.
