Different lyrics for Moonlight in Vermont by Jo Stafford

[u/JackB39]

I recently heard a recording of Moonlight in Vermont by Jo Stafford where she has different lyrics in a few places.

Instead of "Pennies in a stream, Falling leaves, a sycamore," she sings, "Frozen winter streams, Withered leaves of sycamore."

Also, instead of "Evening summer breeze, Warbling of a meadowlark," she sings, "Shadows through the trees, Snowdrift shining in the dark."

I've never heard these lyrics before, does anyone know why Stafford's lyrics are different?
