A lot can happen in a year, especially if you are a member of Yes. Last fall former members — singer Jon Anderson, ’80s-’90s era guitarist Trevor Rabin and keyboardist Rick Wakeman — reunited to form a new band called ARW (for Anderson Rabin Wakeman) playing the Yes catalog. Earlier this year, Yes entered the Rock and Roll Hall of Fame, and ARW legally changed its name to YES featuring Jon Anderson, Trevor Rabin and Rick Wakeman. Meanwhile, another version of Yes is touring with guitarist Steve Howe and drummer Alan White.

The progressive rock trio invades Long Island this weekend, performing at LIU Post’s Tilles Center on Sunday. Calling from the road in Minnesota, Anderson opens up about this dual reunion/new venture.

What made the three of you come back together?

I’ve been touring with Rick for years so we’ve always been in touch. Over the last 10 years Trevor has been working in Los Angeles on movie scores. We kept up a good friendship and I told him, “If you ever get time off from movie scores, I’d like to get together with Rick, go on tour and make some music.”

How did the “Yes” name come back into play?

I always owned part of the name. When we got in the Rock and Roll Hall of Fame and people saw us on HBO all over the world, I thought we should be really calling ourselves Yes between me, Rick and Trevor. It just seemed logical.

What’s your impression of the other Yes?

It’s a different kind of band. They are still playing Yes music, songs I wrote . . . hey, I don’t mind. A lot of bands play Yes music — like tribute bands all over the world.

You reunited with Steve Howe and Alan White at the Rock and Roll Hall of Fame induction. How was that?

It was a lot of fun. We enjoyed it. We started to think about the fact that it’s 50 years of Yes next year. It’s a milestone.

Did you ever think it would last this long?

When you start a band you think, maybe two or three years you can keep it going. But here we are 49 years later. It’s like climbing a mountain and here we are at the top. Next year will be the wonderful musical climax of the band’s adventure in the crazy world of Yes.

What do you have planned for 2018?

Rick, Trevor and I wrote a lot of music, and we are going to get it recorded this winter. I think next year will be very musically adventurous.
