An appearance at the 1969 Newport Folk Festival helped launch Kris Kristofferson's storied career, and on Saturday (July 23), the iconic singer and songwriter returned to the 2016 iteration of the festival for a surprise performance, joined for a song by up-and-comer Margo Price.

After being introduced by Newport Folk Festival producer Jay Sweet, Kristofferson and his band performed on the fest's Quad Stage. With Price, the country icon sang "Me and Bobby McGee," a song penned by Kristofferson and made famous by Janis Joplin in the early 1970s. Readers can press play on the video above to watch Price unassumingly walk out a few lines into the tune; the rising star offers harmonies and grooves along for most of the song before taking the lead near the end of the performance.

During his introduction of Kristofferson, What's Up Newp reports, Sweet shared with the audience the story of how, back in '69, it was Johnny Cash who convinced Newport Folk Festival founder George Wein to let Kristofferson perform at the event. Kristofferson also performed "Me and Bobby McGee" at the festival back then, during a short set that gave his then-fledgling career a big boost.

On Facebook, Price calls her performance with Kristofferson "the highlight of my musical career so far." The singer-songwriter performed her own set at the festival following her stage time with Kristofferson.

After years of memory loss, things are looking up for Kristofferson: The singer and his wife recently revealed that he was misdiagnosed, and that the root cause of his troubles is Lyme disease. Things still aren't perfect, but since undergoing treatments for the disease, Kristofferson has been doing much better.
