Truckin'
"Truckin'" is a song by the Grateful Dead, which first appeared on their 1970 album American Beauty. It was recognized by the United States Library of Congress in 1997 as a national treasure.
Written by band members Jerry Garcia, Bob Weir, Phil Lesh, and lyricist Robert Hunter, "Truckin'" molds classic Grateful Dead rhythms and instrumentation with lyrics that use the band's misfortunes on the road as a metaphor for getting through the constant changes in life. Its climactic refrain, "What a long, strange trip it's been," has achieved widespread cultural use in the years since the song's release.
