Dolly Parton is among an eclectic list of musicians guesting on the upcoming album from Yusef, the iconic singer-songwriter formerly known as Cat Stevens. Parton sings with Yusef and Paul McCartney on the project's first single, 'Boots and Sand,' with a video shot by Bob Dylan's son, Jesse Dylan.

'Boots and Sand' was inspired by a real-life incident that happened to Yusef in 2004. He was denied entry into the U.S., apparently because he was mistakenly identified as one of the names on the post-9/11 no-fly terrorist list.

"It's a slight oddity of a song," Yusuf tells Billboard. "The image I had was kind of a cowboy B-movie made in Italy, but the story came from real events, real people."

Pop-country singer Michelle Branch, formerly of The Wreckers, also guests on the album. She sings with Yusef and Gunnar Nelson (of the rock duo Nelson) on the track 'To Be What You Must.'

Yusef's yet-to-be-titled CD is a followup to 2006's 'An Other Cup,' his first secular album in 28 years. He says the new project is a throwback to the kind of music that originally put him on the map.

"This one was really a result of me writing a lot of songs and being kind of inspired again," he explains. "After I recorded ('Cup') people just wanted to hear me do a lot of simple stuff, just with the guitar."

Yusef's new album is due in late spring.
