Lee created Gadyloo after her previous fanzine, Caravan, became so successful that she found it difficult dealing with advertisers. It was a mimeographed fanzine that ran for six issues. By issue 5, published in 1959, it consisted of 26 pages and was duplicated on various colours of paper.
Contributors included Dave Beadle, Roy Berkely, Oscar Brand, John Cohen, Dick Greenhaus, Woody Guthrie, Lori Holland, Alex Kochanoff, Mark Morris, Paul Prestopino, Dave van Ronk, Mike Seeger, Don Shapiro and Winnie Winston. The zine frequently covered the exploits of the group the New Lost City Ramblers.
Gardyloo was sold at Iazzy Young's Folklore Center in Greenwich Village, NYC.
