Miley Cyrus, 'Butterfly Fly Away' Feat. Billy Ray Cyrus (Sessions)

Emily to Miley: Miley, how does collaborating across different genres influence you musically? What is your dream collaboration?

Miley: If I could work with two different people, it would definitely be John Lennon and Johnny Cash, but I'm out of luck both ways. I would want to write with Johnny Cash, and I would want to perform a song that John Lennon wrote 'cause I don't think I can write with John Lennon. He's too genius and I would just end up messing it up. You can't make it better. It's already at its best.

Emily: Good point.

Miley to Billy Ray: What is the best concert you've ever been too?

Billy: I love thinking back to, you know, when I was a kid going to bluegrass festivals, and seeing people like ...

Miley: That sounds like torture.

Billy: JD Crowe and the New South, Charlie Daniels and Earl Scruggs -- just a bunch of feel good music, you know. I look back on that and go, "Wow, life was such a simpler time." I still remember going to see Wayland Jennings and Willie Nelson, and the Outlaws Tour, and going for the first time ever to see Lynyrd Skynyrd. It's all of those styles that make me who I am to this day. It would be hard for me to narrow it down to just one. I do gotta say, the other day when we saw ZZ Top. Go see ZZ Top. You will be in for a rockin' ride. It was unbelievable.
