MMario, i've heard of at least two "wild geese" songs, one a "pop hit" back in the '50s by, i think, "frankie lane" ("i must go where the wild goose goes, for my heart knows what the wild goose knows...") the other is, i think, a kipling poem set to music and sung by, i think, again, "kathy mar" a quite good sci-fi/fantasty "filk" singer, this one would likely be the one heinlein was thinking of since an affection for "good ol' rudyard" is rather common in sci-fi fan circles, me included since i live about 3 miles from his former home in vermont up on black mountain road. i'm about to hit the sack, got duty at 0600 so up at 0400 but i'll get into my copy of "time enough for love" when i get a chance (soon) and get back to you. the "kathy mar" song is currently available on tape, i'll look up the source and pass that along too asap.
