When I was a child, I had a kiddie album (yes, it was pre-CD) titled "Candy Man" - it was a musical story based on (rip off of) Sammy Davis Jr's hit - not a crazed serial killer.
ANYWAY - the protagonist is Princess (i believe her name was) Prunella - and her shtick is that she's always sad - she sings a song that, to this day, and especially this weekend, goes through my head whenever things don't go my way...
I'll never be happy again.
I'll never be able to smile.
To laugh at a joke, like similar folk,
I guess it's not my style.
I'll never be happy again!
