Stories about the Grateful Dead, as with any number of other bands, often relate events that are wild, outrageous and salacious - of the "cannot believe they did this" variety.
And while some of that is certainly true of the actual history of the Grateful Dead, my research indicates that the various members of the band were particularly prolific as authors themselves.
None of this to be confused with a book entitled The Grateful Dead: The History of a Folk Tale, available for free legal download from the gutenberg project.
On one hand, we can claim that any songwriter is, by definition, an author. However, the blog-task as I interpret it, would have us looking for musicians who have gone outside their lyric-writing realm to put pen to paper in an endeavor separate from their musical one.
Among the 157 books listed in a Google search for Grateful Dead books, we have Bill Kreutzman's Deal, Phil Lesh's Searching for the Sound, Garcia's Harrington Street, Garcia's A Signpost To New Space; Mickey Hart's Songcatchers and his Planet Drum, Drumming at the Edge of Magic, Spirit Into Sound.
A Box of Rain, credited to lyricist Robert Hunter may not count (it appears to be the published collection of his lyrics), but his novel Dog Moon does. Bob Weir's extracurricular authorship - as best I can discern- seems to be limited to writing forwards for the books of various other authors.
Left over from my aborted attempt to post about The Road, we have A Long Strange Trip: The Inside History of the Grateful Dead; Living with the Dead: Twenty Years on the Bus with Garcia and the Grateful Dead; Home Before Daylight: My Life on the Road with the Grateful Dead; So Many Roads: The Life and Times of the Grateful Dead; Grateful Dead: the Illustrated Trip; No Simple Highway: A Cultural History of the Grateful Dead; Goin' Down the Road: A Grateful Dead Travelling Companion and more. These book titles in addition to no small number of Grateful Dead song titles are clear evidence of the importance of the road for the Dead. For any search for meaning in the trip through life, for that matter.
Because it is a song about writing a song, we'll go with Ripple.
If my words did glow with the gold of sunshine
And my tunes were played on the harp unstrung
Would you hear my voice come through the music?
Would you hold it near as it were your own?
It's a hand-me-down, the thoughts are broken
Perhaps they're better left unsung
I don't know, don't really care
Let there be songs to fill the air
