At one point in time, American folk music crossed over from the time-frozen traditional--then sold mass-market by Burl Ives--to the more iconoclastic as represented by icon-in-his-own-right Bob Dylan. After awhile, given America's 20th century social upheaval, it was no longer as easy as it once was to care whether or not Jimmy cracked any corn. Peter Paul and Mary lived during both eras and managed to survive in both. This album more than any other represents their "border crossing"--and it contained two of their most popular songs: a faithful rendition of John Denver's "Leaving On a Jet Plane" which I heard years before Denver's own version and "I Dig Rock & Roll Music", a tribute to the Mamas and the Papas, the most successful mixed-gender folk rock group of all time. Despite these two powerful radio hits, however, the most powerful song in here is the antiwar anthem "The Great Mandella", a simple yet dynamic tune about the head-on collision between the World War II generation and the Boomer generation over the Vietnam issue. The beauty of this song is that none of the three verses is "in the voice" of the protester himself as was usually the case with an antiwar song. Verse one is from the viewpoint of his infuriated father, the other two are quasi-journalistic views by society in general of his imprisonment and hunger strike. As Tom Brokaw rhapsodises over "The Greatest Generation", it is easy to forget that this particular generation saw no other practical use for their male issue than as cannon fodder. Very practical--neither we nor the Vietnamese they had sent us over to fight were seen as being worth the powder to blow us to Kingdom Come. And thanks to sound recording (invented well before the birth of either generation), this album with this song on it are still available to set the record straight, Brokaw's efforts notwithstanding.
