Not to worry. Any good song needs to be swirled around, now and again.
I never could sing "Len's a match" as in the first verse. Yes, I know what it means now but I'd rather not stop and explain it every time I sing the song. Instead, I sing "No one could ever match."
I wasn't captured by this song until I heard Margaret Walters and John Warner sing it, with four verses, at a house party in Sydney, Australia.
