I remember only fragments of this song, but it ended, as far as I can recall, thus:
"Come into the garden, I've a secret word for you,
Come into the garden, I'm a Lortle(?) too".
What the heck a Lortle was, I have no idea, except that I remember it as a made-up word particular to this song. If you were a Lortle you kept it quiet. Was it a code-word for "gay"? Maybe, but I wouldn't have cottoned on at the time. The playground word of the time was "mo", short for "homo", and I'm pretty sure I hadn't heard it then and certain I didn't know what it meant.
Has any kind person out there come across this song? Remember the rest of the words? Or did I dream it?
