Byron's "So We'll Go No More A-Roving" has been set to music by Richard Dyer-Bennet and can be heard on his first recording on his own label, Dyer-Bennet Records No. 1.

So we'll go no more a-roving
So late into the night,
Though the heart still be as loving,
And the moon still be as bright.

For the sword outwears its sheath,
And the soul outwears the breast,
And the heart must pause to breathe,
And love itself have rest.

Though the night was made for loving,
And the day returns too soon,
Yet we'll go no more a-roving
By the light of the moon.

He has also recorded "Spanish is the Loving Tongue" (by Charles Badger Clark Jr., original title, "A Border Affair"). I'm not sure if he wrote the tune or if someone else did. A couple of people have set Yeats' "The Song of the Wandering Aengus" to music. I think Jean Redpath has recorded one version of it.

Tons of stuff out there.
