So we started using Shout in our show and when I went to Decca for my audition, that was the song I sang. Afterwards, they said 'Very nice, dear, now that'll be your first single.' I was heartbroken. I was hoping I'd get a Lennon-McCartney song written for me.
Of course, it was a huge hit, so they'd proved they were right and, after that, I tended to do what I was told.
