Was aware of them in the 70's through songs such as 'Yellow Submarine' & 'Ob la de ob la da'.
The publicity after John was shot made me more aware. Then my dad gave me the 67-70 Blue album. Still remember the magic of hearing those songs for the first time.
Slowly built up a collection of Beatles albums. Last album I bought was 'Let it Be', 10 years later. Not sure why I left it so late, as it's a great album.
