Under the Willow Tree looks similar to the Morris song

Various versions:
Under the willow tree ("Don't you remember the vows so tender ...")
also Willow tree ("Oh take me to your arms, love ...")

"Why did you say my lips were red, and made the scarlet pale"
makes more sense, too

Under the Willow Tree

There are several other songs there, including The Willow Tree, and a parody of it, The Apple Tree

The willow tree ("O take me to your arms my love ...") starts the same as the other one, but is a different song

This is also another song:
The old willow tree ("One evening in the month of May, while strolling in the fields ...")
Performer: Coyne, Fred; Clindes, Pete
