Rainbow Quest

[1] Toshi actually functioned as the show's director by default due to the fact that she continually made suggestions to Rubinstein that he, in turn, would pass along to the camera operators.

Many of the other shows featured film clips made by the Seegers during their travels in the U.S. and elsewhere, including a demonstration in Mexico of guitar-making and another in the West Indies of making a steel drum.

The shows were broadcast by Channel 47, primarily a Spanish-language outlet, to a very limited audience because only televisions equipped with a UHF antenna and tuner could receive them, and reception was difficult in an age prior to cable.

Among the guests featured on the program's 39 episodes were The Beers Family, June Carter, Johnny Cash, Judy Collins, Elizabeth Cotten, Cousin Emmy, Reverend Gary Davis, Donovan, Richard Fariña and Mimi Fariña, Roscoe Holcomb, Mississippi John Hurt, Sonia Malkine, Mamou Cajun Band, Shawn Phillips, Bernice Johnson Reagon, Buffy Sainte-Marie, Patrick Sky, The Stanley Brothers, Sonny Terry and Brownie McGhee, Doc Watson, and Hedy West.

The Clancy Brothers and Tommy Makem and Tom Paxton appeared on the first show of the series on short notice because Seeger felt ill, as he explained on camera.

A clip of Tommy Makem singing "The Butcher Boy" during this initial episode appeared in Martin Scorsese's Grammy-winning documentary about Bob Dylan, No Direction Home, which focused on his earliest musical influences.

At the suggestion of Manny Kirchheimer, an independent film maker whose wife Gloria was an editor at Clearwater Publishing, the decision was made to seek a grant for the work and a proposal was prepared under the aegis of The Woody Guthrie Foundation, whose director, Harold Leventhal, was also Pete Seeger's manager.

Because Clearwater's marketing efforts were primarily directed to libraries, sales were sparse through the '80s and '90s, especially prior to the advent of the Internet, and only a few thousand cassettes were sold in total.

His blog post, with streaming players for the videos, originally included a footnote stating that "The show has been in the public domain since the 1990s"; he has since edited his comment, noting that he "cannot confidently characterize the copyright status of this work".
