WELL ... since we all here are just speculating ... how do we know for sure SP would not have re-joined at some point (after he have had his surgery and re-gained his strength)? Remember ... he didn't say “you guys can’t go on without me” ... just to “leave the Journey name alone” – (maybe) until he’s healthy and able to come back.
Seems to me Neal/Jon broke the bond by hiring and announcing SA as the new lead singer of Journey -- instead of simply referring to SA as a new bandmember for touring (ala Randy Jackson and Mike Baird for ROR). By taking such a drastic (permanent) action, they effectively shut the door. I don't care how many times Neal mentions "open invitation." Given SP's sensitivity and pride, is he going to crawl back to the house he helped built through many years of sweat and tears when another man(now men) have moved into the master bedroom? It was Jon that related this Steve quote (on the BTM show): "You know, there's no going back." I think we can all agree that SP (probably) is a man of his word.
So ... why nothing for 12 years? I really don't have an answer to that as I have no clue to the inner workings of the man. I don't, however, buy the premise that his preference was always as a solo artist ... so therefore, it proves he either would not or could not sing anymore, so therefore, Journey would be waiting in vain.
Whether one believes him or not ... SP has said it was Neal's outside efforts that prompted him to go solo with Street Talk. And, referring back to those ST promo interviews, Steve was already talking about doing 1 more solo album to complement ST. AgainstTheWall was a false start, but FTLOSM stucked. Again, referring back to past interview articles …when asked why he was touring solo (without the Journey guys), his answer was always “why not?” Everyone was into something different at the time. It was only natural that he did his own thing, too. However, he was never quoted as saying they were through. How many musicians are both solo and in bands? Too many to count. There simply is no factual basis to determine that SP cared only about soloing and not singing with Journey.
I would agree Sony (through JohnK.) pressed the issue to get the band back together. I believe, too, that all band members involved realized that, together, they are(were) more successful than separately. I don’t think anyone needed much arm-twisting to get back together for TBF. Shame everything had to end the way it did. I guess it just adds fodder for the many factions of Journey fans to debate over …and why we bother to come to this forum in the first place
