Oh don't worry, I got the reference. I know the song quite well. I grew up listening to it and many others by PP&M.I guess you're not as old as you seem. ;-)
It's an old Peter, Paul & Mary song from their debut album issued in 1962, the heyday of American folk music. Here's a link to the original song: Peter, Paul & Mary - Lemon Tree - Free MP3 Stream on IMEEM Music
