I can hear what you mean now but I remain unconvinced. "Definite" is a bit strong a description for the very light glottal stop I'm hearing. To me it just sounds like he rushed the next syllable a bit. I'm not convinced he's singing the wrong word. As it happens, Mike's diction was never particularly good, right into adulthood. Needless to say, however, as that a capella mix proves, he was a phenomenal vocalist.
