Some of Nashville's finest songwriters sang their classics at Vince Gill's 50th birthday party Thursday (April 12) at his home in Nashville. Performing on a backyard stage sheltered by a large tent, Thom Schuyler kicked off the event with his affectionate homage to Music City composers, "16th Avenue." Don Schlitz reprised his mythic "The Gambler." Janis Ian rolled back the calendar to 1975 with "At Seventeen." Rodney Crowell sang "'Til I Gain Control Again." The Nitty Gritty Dirt Band's Jeff Hanna favored the crowd with his rendition of Jerry Jeff Walker's "Mr. Bojangles." Others who took their turns at the microphone included wife Amy Grant, daughter Jenny Gill, Leslie Satcher, Al Anderson, Fred Knobloch, Beth Nielsen Chapman and Gill himself. Also spotted in the crowd were Bill Anderson, Del McCoury, songwriter Matraca Berg, guitarist Pete Huttlinger and music executives Bruce Hinton, Tony Brown and James Stroud.
