Country music legend Willie Nelson has been named an honorary doctor - of music.

The 80-year-old Texan was honored Saturday by the Berklee College of Music in Boston, along with musicians Carole King and Annie Lennox.

"I was going to ask them if I could write my own medication," Nelson told the Boston Globe before the ceremony. "Probably not, but it doesn't hurt to ask."

Nelson has long been a staunch advocate of decriminalization of marijuana and has had his share of drug-related brushes with the law.

The new "doctor" seemed to revel in his title, tweeting a picture of himself sporting his trademark long braids and wearing graduation regalia.

"Dr Willie looks great," he wrote.

Lennox, best known as one half of the Eurythmics duo, delivered the commencement speech to more than 1,050 graduating students and their guests at Agganis Arena, one night after she and Nelson took to the stage separately to perform with students at the school's commencement concert.

Berklee has previously bestowed the honor on some of the most influential names in music, including Smokey Robinson, Aretha Franklin and David Bowie, according to the school's website.
