Me too, I ate one sour too.
Does the OP mean the first words sung / spoken by an artist on their debut?
In which case, Patti Smith's "Horses" kicks off with "Gloria" - "Jesus died for somebody's sins but not mine".
Ha! Great minds...
That was the idea. I just thought that line from Elvis Costello was a magnificent way to announce yourself to the world and wondered who else had arrived with such verbal aplomb. Patti Smith is a good call.
