Healy explained on his blog at FranHealy.com
that as a way of thanking McCartney, he became a vegetarian. Said Healy: "One of the biggest coups was getting Paul McCartney to play bass on a song. I'm not sure what non McCartney songs he's played bass on but I couldn't think of many. Anyways his bassline is brilliant. (Healy's wife) Nora and I were sitting and were thinking of a thank you present and I suggested going vegetarian. Our son is already one so it would mean we would all on the same boat. I met Paul at his show in Berlin and told him what we wanted to do. He was visibly flabbergasted. Three days later the Fed Ex man delivered three Linda McCartney cook books."
