There's also the early 20th century novelty song "Come Take a Trip in My Air Ship" which has been discussed and posted in the threads.

Another "newer" favorite has to be Pete Seeger's singing of "Martian Love Song" which is on his 1958 Gazette recording by Folkways Records; don't know if that one has been posted but with encouragement I might do that.

Cheerily,
