Kelly Jones believes his former Stereophonics bandmate Stuart Cable would have ended up back in the band if he'd lived.
Stereophonics frontman Kelly sacked his old friend and bandmate in 2003 when his drink and drug abuse became problematic.
The pair patched things up in just over a year and at the time of drummer Stuart's death (he vomited in his sleep and choked) they were on good terms again.
"If he'd lived I think he'd have ended up back in the band," the Welsh singer said.
"What happened between us was stupid and if we'd been more patient at the time I think we could've ironed things out then. After all, we're only a band."
The band are back with their eighth album Graffiti On The Train and Kelly is pursuing funding to adapt his Graffiti On The Train screenplay into a film, which he hopes will be released in "two or three years".
"Lots of things started unfolding as I was writing the album," he said. "At the same time I started writing a screenplay about these two kids who leave a small Welsh town to go across Europe to watch bands. There's an element of autobiography in that."
He added: "The two things I was writing sort of bleed into each other. There's the thread of a story there, it's not a concept as such, and I was taking inspiration from one for the other and vice-versa. Plus I've got a ready-made soundtrack for the film if it gets made."
