Had he not died in that bathtub in Paris in 1971, Jim Morrison would be 60 years old when The Doors of the 21st Century perform tonight at Oneida Bingo & Casino.

Two original members of The Doors are in D21C — keyboardist Ray Manzarek and guitarist Robby Krieger.

Known as a band without a bass player, D21C now tours with bassist Angelo Barbera. Filling Morrison’s leather trousers is Ian Astbury, formerly of British goth-rock band The Cult.

Original drummer John Densmore filed suit to stop the other two members from touring as The Doors (hence the elongated name), as have Morrison’s parents and the parents of Pamela “Cinnamon Girl’’ Courson, Morrison’s girlfriend and heir.

Ty Dennis, who now fills the drummer’s chair, replaced original D21C drummer Stewart Copeland after he broke an arm in a biking accident and subsequently sued the band.

Dennis, who was born the same year Morrison died, responded to a few e-mail questions.

How does it feel to play in a band that peaked before you were born?

“I never even thought about that. I guess it is pretty interesting that I now am playing with Robby and Ray 33 years later.”

What about sitting in the chair once occupied by Densmore and then Copeland?

“All I can say is that when I got the call to come down and play — meet Ray and Ian — I didn’t let it intimidate me that Stewart was playing before me. I would never, ever try to be John Densmore or Stewart. Their playing is so classic and unique. I think playing the way I play and not cloning someone else is a big reason I’m playing with them now. It’s much more challenging to put your own spin on things than to just blatantly copy someone else. I play the way I play, but, of course, I incorporate a lot of John’s parts and ideas that are just so awesome and essential to those classic songs.”

Can people expect to hear a recreation of The Doors?

“There are a lot of Doors tribute bands you can go see for that. Being that Robby and Ray are a large part of The Doors’ sound, the band definitely brings many elements that have always been part of what The Doors do. To Robby and Ray’s credit, I think they picked players for The Doors of the 21st Century that are good at bringing elements of the classic Doors sound but also add their own thing. They aren’t stuck in what they’ve done in the past. I am very aware of keeping with the true spirit of The Doors’ sound, and from a drummer’s point of view, I really enjoy that challenge.”

How does Ian do in Morrison’s place?

“Ian does a fantastic job. These are very big shoes he has chosen to fill, and he approaches it not as trying to copy Jim but by honoring him. Ian really is a Doors and Jim fan first and foremost before being the ‘new singer.’ I can say firsthand from working with Ian that he is very consistent and a pro, and he gives a great show every night.”
