Spanish is the loving tongue, sure it is.

As far as I know, this is the only Dylan live performance of "Spanish is the loving tongue", the other ones are studio takes. It was recorded in San Antonio, Texas, in 1976.

Another really nice take that comes from the Friends of Chile Benefit Concert is the duet between Bob Dylan and Dave Van Ronk. An awesome take that should have been in the Brothers Coen's Movie "Inside Llewyn Davis". The song is "Spanish is the loving tongue" in an outstanding version.
