Dictation: Searching for Lambs
Here is a MIDI realization of the tune. It is more regular than any performance.Here are a few nice performances. There is a lot of variability in the degree of rubato and even in the meter, especially the timing between phrases.

Once the voice comes in, around 0'35", this performance is about as regular as you'll hear, both in meter and tempo.

"Classicized" but very beautiful.
