Description: ''There's nothing like a Grateful Dead concert.'' Chanted at every concert, those words say it all. There really is nothing like a Grateful Dead concert. Fans knew they would encounter friends, old and new, at all the shows. Swaying and dancing to the melodies, many "Deadheads" would follow their favorite band from show to show. Author Michele C. Hollow has interviewed Bob Weir, lead singer, guitar player, and songwriter for the Grateful Dead; Dennis McNally, the Grateful Dead's publicist for over twenty years; as well as David Gans, the radio host of the nationally syndicated "Grateful Dead Hour."
