The one that bugged me the most was "Reuben and Rachel".

Yes, leeneia, "If I Had a Hammer" does have chords. It sounded quite rousing when done by Peter, Paul, and Mary in the early sixties...but it's the kind of song that has a fairly short shelf life, and probably should not be performed by anyone except the original act.

Mike B. - A cigarette tree is a tree on which grow cigarettes ("Nature's Own" brand), fresh and ready to smoke, and best of all, free! This was apparently a hobo's dream back in the time depicted in that song. Soda water fountains? Same deal. Lemonade springs? More of the same. Is it a silly song? Yeah, but it's supposed to be whimsical. Burl Ives used to sing a lot of such whimsical songs, and they were thought of as "folksongs" at the time. There were so damn many songs about hobos back then...I don't know why people were so fascinated with that theme...but it may have partly had to do with all the people who bummed their way out west during the Dust Bowl and the Great Depression.
