Pretty much. It's been a while since I read the book but it's something like. KK was playing with another guy. The band that would become JP had been playing gigs for a little while and despite knowing KK, who I believe had left home to be a rock star and was living hand to mouth in some little one room flat no one could reach him at, hadn't asked him to play. He tried a few times to use what he describes wasn't even a friendship with Ian Hill to get into the band but there was no vacancy. It wasn't until the night he saw the band in their van with JP written crudely on the side panel that he decided the name was good and pressured them even more. It was months, if not more, between KK first trying to weed his way into the band and it actually happening and I think from memory it was weeks between when he saw the JP name and he got into the band. So claims than he formed JP are bullshit, they were a band before he joined, they had a name, it was just that by the time he joined they were falling apart and three of them pretty much rebuilt it.
