There are lots of people here with an interest in grammar, but there aren't many grammarians. The internet gives us all a great opportunity to show off our ignorance!

Songwriters are usually governed by rhythm and rhyme. The desire to satisfy these two difficult masters/mistresses often leads to artifice.

David Crystal, a real grammarian, writing on Paul McCartney's Live and Let Die; In the case of the song, the rhythm of the piece asks for unstressed syllables at both ends - imagine how it would sound if the line ended on live, with an elongated vowel - and that is what we get. Wronger and cuter it certainly is. When music calls, grammar bends.
