Here's a reunion of some early members of The Byrds singing their most famous hit..
Crosby has a colorful history in music (and in and out of jail and rehab) and is probably best known of late for surrogate fathering Melissa Etheridge's children, but his harmony voice was among the best at one time. Chris Hillman, also in "The Flying Burrito Brothers", later formed the Desert Rose Band in the late 80s with John Jorgensen (seen in the background) and Herb Pedersen. Hillman played bass in The Byrds (and on this video) but Pedersen took over bass duties in DRB. A not-so-good quality video of "Running" can be found here. DRB continued the biblical theme of "Turn, Turn, Turn" in some of their California folk-bluegrass songwriting but the country market basically dried up for them in the mid 90s.
