I heard the original to this on my Dad's old records. It was by a man but I don't know who.

Well The radio said well you better watch out, here come the little green men,
And if they land in your back yard then you better not let'm in.

Well I just ignored my radio and stepped out on the lawn,
And there was a couple of little green men, they were swingin' it arm in arm.
Sing'in, bodeloolop, bodeloolop, bodeloolop bum

Well I knew that I should have gone to bed when I took one look at their pointed little heads, figured any minute now I'd be dead if they caught me hangin' roun. But it seemed so far back to the stairs that I just commenced to sayin' my prayers, when I heard that funny little beat of theirs and I started to dig the sound. It went:

bodeloolop, bodeloolop, bodeloolop bum


Well they danced around for an hour or two and then they discoverd me,
And one of the men said double-eck, double-oh and double-oh, gigalo fee,
Which means take me to your leader boy I'll tell you in advance,
Now up on the moon we dont have jive, so we come down to earth to dance.

And through every US radio station, the little green men spoke to our nation, then we caught a translation of the funny little tune,
Saying, "See ya' later, alligator. Plant ya' now and dig ya' later." Up went the itty-bitty escalator and they flew back to the moon. Singin

bodeloolop, bodeloolop, bodeloolop bum
