When I lived in New York City I must have run into Gerome Ragni, the co-writer of the book for “Hair,” 20 times at our neighborhood pub.

Every single time he told me he had written “Hair.” Every single time I bit my tongue and didn’t respond, “Gerry, did you write it on the back of a matchbook cover?” It is an understatement to say the book of that musical is exceedingly thin, although Ragni must be given credit for his and James Rado’s lyrics.
