techinally yes, Jon did bring in 30 songs from his scraped solo disc for the album that would become crush. some are in bootleg form, some made Crush , some are b-sides, and some are on the boxset. IMO Stay was released under the Bon Jovi moniker, it is a crush b-side; and sounds very much like a classic Bon Jovi ballad. IMO If it had been deemed worthy enough by Jon it would have been put on Crush; and stayed pretty much the same as we know it today. Jon also had most of Keep the Faith written prior to the band getting back togehter; after the first hiatus. Jon is the primary person that drives the band.
