Willie Nelson, Annie Lennox and Carole King have been handed honorary doctor of music degrees for their lengthy careers.
The trio received the honours from the Berklee College of Music in Boston, Massachusetts on Saturday, and the former Eurythmics star stepped up to deliver the commencement address at the Agganis Arena.
Lennox told the audience, "Consider this... wherever you think you're heading right now might turn out to take a completely different path. What looks like an ending might actually be the start of a brand new beginning.
"Wherever and however we find ourselves, what a privilege it is to enrich our lives through music: the incredible universal language of the soul. Enter it wholeheartedly, make it yours to share with the world in the very best way you can."
All three singers took to the stage during the ceremony, and country star Kris Kristofferson presented his pal Nelson with his doctorate.
Previous honourees include Aretha Franklin, Loretta Lynn, Billy Joel and David Bowie.
