How Long Has This Been Going On. Produced by George Martin, recorded at Air studio, Main Hall. I remember George introducing me to Jon at in the studio and thinking I must be in another sub human group to this guy. Not that he wasn’t really nice, he was, really nice, but he looked gorgeous. Anyway, he sang through the song the first time a 4th up and somehow with his rock voice it wasn’t graiting, it sort of worked. Once he was given his starting note he sang it live with us and his voice brought tingles to my spine with it’s power. I loved it, so there! I’ve just had a listen and the bass part is nice, you can tell I was digging it!
