The Wikipedia article goes on to say the Byrne improvised the lyrics. In any case, I don’t remember anyone but Byrne writing his own lyrics, regardless of who has songwriting credit. I remember he was on the tonight show or letterman, can’t remember which, where he said something to the effect of “I pick sounds to fit the music then I pick words to fit the sounds”, but I never believed that’s how he really came up with his lyrics.
I believe that would be Tony Cochran
