The Number One's for the nine months before and after you were born - gives a great flavour of the time. 

Note to self - Idea for dragons den - compile them for people and sell them for birthdays.  There's a great selection of artists during that eighteen months spanning from Jim Reeves (am I really that old?) to the Beatles, Rolling Stones, Monkees, Trogs and Procul Harum.  And in the mix - Frank Sinatra, Tom Jones, Petula Clark, Beach Boys.

What's interesting is that almost all the songs from that time would still be recognised.
