  Not all that uncommon actually. They were all taken from a melody written by Mozart (I think?). During that Era and up until the late 1800s, it was very common to repurpose melodies with new lyrics. Another famous example is the american song the "star spangled banner" which takes its melody from a British drinking song called "anachrion in heaven." >
