Good memories and J.S Bach

I remember this song from a perfume advertisement..., everything's gonna be alright everything's gonna be OK..., na na na na na na na naaa na naaaa. The Bach's song was a bit hidden but everytime the ad turned up on TV my flatmate Marta told me: Listen Roci.., it's Bach. Nowdays, air on a G. String is one of my favourite songs.., I love it.
