maybe repetitive, simplistic, predictable, sickly candysweet plagiarism but don't care, love it to bits.
Tune! I can remember when I was about 10, I really fancied a girl in my swimming group and I used to fantasise that I would take her on a picnic and sing that song to her.
and I always wanted to ask him what the last line of the song meant.. Too late now as I think he's gone sadly. (8th Jan 2017 RIP Peter).
