The best version of this haunting Utah Phillips song is the one by Joan Baez. But it has been removed from YouTube.  Here is Rosalie Sorrel's version.  And here is Dylan's.

If your ladies was blackbirds/And your ladies was thrushes/I'd lie there for hours/In the  chilly cold marshes/If your ladies was squirrels, with high bushy tails/I'd load up my shotgun with rock salt and nails.
