Assembled from Joans nationwide tour of Autumn 1961 through to the Spring of 1962, Joan Baez In Concert showcased the wide variety of material that Joan featured in her show, ranging from gospel (Gospel Ship), blues (Babe Im Gonna Leave You), message songs (What have They Done To The Rain) to African traditional (Kumbaya) through to Brazilian love songs (Ate Amanha, which is sung in Portuguese throughout).   It was Joans version of Babe Im Gonna Leave You that brought the song to Led Zeppelins attention, although their version would end up entirely different from Joans!
