Roger McGuinn (born James McGuinn III) is most famous for being a founding member, singer, guitarist, and songwriter in The Byrds. Since that band's demise he has had moderate success as a solo artist, working with many other artists, including Bob Dylan and Tom Petty. Some of his solo material has appeared in films, such as 1969's Easy Rider.
