Zac Brown Band has collaborated with legendary artists spanning genres, and frontman Zac Brown revealed two stars he hasn’t worked with yet that are “on my bucket list.”

The nine-member band has teamed up with Avicii, Jimmy Buffett, Sheryl Crow, Sara Bareilles, Alan Jackson, Cody Johnson, Blake Shelton and many others over the years. When asked in an interview with Inked magazine which artists he’d like to work with someday, Brown replied:

“I would love to do a song with Adele — that’s on my bucket list. She is my favorite female voice of all time. Paul McCartney is on my bucket list as well. There are so many of my favorite artists that I’ve gotten to meet and hang with, but not create with. The list is long.”

Throughout the conversation, Brown also spoke about Zac Brown Band’s newly-released EP, the stories behind his tattoos, the highlights of being a father to his five children, and more. Find the full interview here.

Zac Brown Band released No Wake Zone last month. The 5-track EP includes a tribute to late music legend Buffett (“Pirates & Parrots,” featuring Mac McAnally), “Tie Up,” “Two Blue Chairs & You,” and more. Brown previously said the collection “is all about capturing the essence of relaxation and freedom. We hope this EP provides our fans with a much-needed escape and a chance to unwind.”
