I remember my brother bought "Walking back to Happiness" by Helen Shapiro which included the profound and meaningful words "wompah oh yeah yeah" in the chorus. Then my dad bought The Beatles first two albums for Christmas, ostensibly for me, but I suspect also for himself, my parents became born again teenagers in 1963 when The Beatles emerged on the scene having been shaken out of their classical music only vacuum to embrace all that modern culture had to offer! I wasn't allowed to put them on the record player, he had to do it for me in case I scratched them I was about 9 at the time so didn't have spending power. I think I started buying singles around 1966 when I was about 12, so it would have been The Beatles, Walker Bros, but can't remember what my first purchased single was.
