Barrie, Barrie, Barrie! I have been suffering from this same problem for years! As a teenager, one night I suddenly remembered this little ditty, wrote it down on a piece of paper and stuck it on my wall. I then moved out some years after, my room was painted, the piece of paper was taken down; and ever since then the first line "Eine kleine fliegel flugel aufgeweckene biegel bugel" of the song will pop into my head and drive me mad for days because I can't remember the rest. The only thing I remember is it ends with "birdie".If you should ever solve this little riddle, take out an advert in the major newspapers around the world! PLEASE!
