"The, kind of, go-to phrase that Maurice used in every song he wrote was ‘ba-dee-ya,’ " she says. "So right from the beginning he was singing, ‘Ba-dee-ya, say, do you remember / Ba-dee-ya, dancing in September.’ And I said, ‘We are going to change ‘ba-dee-ya’ to real words, right?’ "
Wrong. Willis says that at the final vocal session she got desperate and begged White to rewrite the part.
"And finally, when it was so obvious that he was not going to do it, I just said, ‘What the f- - - does ‘ba-dee-ya’ mean?’ And he essentially said, ‘Who the f- - - cares?’" she says. "I learned my greatest lesson ever in songwriting from him, which was never let the lyric get in the way of the groove."
