Mark Twain once famously said, “Age is an issue of mind over matter. If you don’t mind, it doesn’t matter.” It’s an adage fiercely embraced by the ever-youthful Judy Collins, on the road celebrating her 85th birthday.

And while artists of her vintage might be expected to be doing some kind of greatest hits tour, that’s not the case for Collins. She is not only promoting her latest record, 2022’s Grammy Award-nominated “Spellbound,” but also her forthcoming book, “Sometimes It’s Heaven: Poems of Love, Loss and Redemption.”

To call the Seattle native a creative dynamo is an understatement, but it’s the only way she knows how to approach life.

“I always say I’m the Betty White of the music industry,” she said with a laugh during a late-January interview. “I have the blessing of having had incredibly good health and incredible stamina. I work out all the time — I’ve been doing that for years.

“I have been given a second career, doing all kinds of things that I’ve wanted to do that I’m doing. And that’s always refreshing. I’ve done a lot of writing. The last book I put out in 2017 was called ‘Cravings: How I Conquered Food.’ I wrote (2011’s) ‘Sweet Judy Blue Eyes: My Life in Music’ before that. I’ve written eight books over the years. I’ve been doing this, singing, performing, telling jokes, writing books and going on tour for 65 years. That’s a long time.”

On her tour, which comes Monday to Pikes Peak Center, Collins said she will mix in material from “Spellbound” along with songs from her deep catalog. As someone who has become known as an interpreter of other artists ranging from Lennon/McCartney and Stephen Sondheim to Train and new wave duo Yaz, her rationale for covering a song is pretty straightforward.

“On this tour, people can expect all kinds of music,” Collins said. “It’s been a lifelong career of falling in love with songs. I have no idea (what attracts me to a song). I fall in love with a song because I fall in love with a song. I am not an analyst. I’m not a music critic. I don’t have any way to put numbers or edginess into it. It’s just a love affair. It’s not unlike how you don’t make any qualifications to a person you fall in love with.”
