That song was by a one name singer called Melanie, and was written by Neil Young. I recall Brand New Key came out during the Jim Croce, Maria Muldaur, Cat Stevens era.
I don’t know whatever became of Melanie.
Neil continues to issue (unrequested) directives to the White House.
Melenie, had a big hit in 70, with “Lay Down” it’s popular name.
I posted it about 3 weeks ago, look up keyword Melenie.
The only song I remember of Maria Muldart’s is “Midnight at the Oasis”-it was okay for a pop tune. And I’ve always thought Neil Young was a loon-probably did too many drugs in his wonderbread years...
"Brand New Key" was written by Melanie herself.
