"Rosie" was actually written for the Bon Jovi album New Jersey
, but ended up on Sambora's vastly under-rated debut solo album.
Running to 4 minutes 49 seconds, it was co-written with Desmond Child
and Diane Warren, the latter of whom, although a fine songwriter is not the sort of name one would immediately associate with mainstream rockers like Sambora and John Bon Jovi. Although the song is an obvious single, it was not released as such. There are bootleg versions which feature the full Bon Jovi line up.
