Bryan Adams took to Twitter to pay tribute to Tina Turner, after her death on Wednesday at 83. The two singers have shared decades-long relationships both as friends as well as professional collaborators.

“RIP my dear @tinaturner I’ll be forever grateful for you bringing me on tour, going in the studio together and most of all, being your friend. Thank you for being the inspiration to millions of people around the world for speaking your truth and giving us the gift of your unbelievable voice. My condolences to Erwin and your family. It’s Only Love…and that’s all. #tinaturner” he wrote along with a black and white picture of Turner and him having a gala time on stage.

It’s Only Love is the song that Adams and Turner sang live on stage in Birmingham, England in 1985 for an HBO music special. This duet was originally recorded on Adams’s album Reckless and released in November of the year before. Here is a video of their performance:

The song eventually culminated in a number of musical projects.

For the December 2018/January 2019 issue of Zoomer, Suzanne Boyd interviewed Adams about his decades-long friendship and collaboration with Turner.

“Tina was making the album Private Dancer, and her producer Carter called me up and asked me to write a song for her, but I was making the Reckless album at the time and didn’t have a spare song … or did I? I asked him if she’d sing on my album and hoped to hear back,” he said.”

He added: “Toward the end of making my album, I heard that Tina was coming to Vancouver as the support act for Lionel Richie. As I hadn’t heard back, I sent a copy of the song to her manager, Roger Davies, who asked if I would meet Tina after her show — which I did, and it was spectacularly Tina. There were a lot of people backstage but I could see her hair coming down the hallway above everyone. It was unmistakable. She shuffled though the crowd, and I could hear her saying, ‘Where is he? Which one is he?'”

He said that the first song that he heard of Turner was River Deep, Mountain High. “There were a few female voices I loved growing up, but Janis Joplin and Tina were my main ones… There were a few female voices I loved growing up, but Janis Joplin and Tina were my main ones,” he said.

Adams also did a photoshoot with Turner in Switzerland.

He also recalled a few of his favorite moments working with Turner. “A couple of favorite moments were in the studio producing her Grammy Award-winning performance of Back Where You Started and then producing her again on a song for the film What’s Love Got To Do With It. The song was called Why Must We Wait Until Tonight, which is another first-class vocal performance,” he added.
