I've been listening to the Melanie (Safka) album 'Candles in the Rain' recently, and 'Lay Down' is one of the cracking tracks on it. Written after her appearance at Woodstock, hence the hippie vibe.
For some reason, until recently, l always thought Melanie was from Wales, but she is from Queens, New York.
Ah well, you live and learn (and l'm an idiot).
Here she is with The Edwin Hawkins Singers on Dutch TV, so you can hear the full version.
