Long was the organist at St Peter le Poer. He is represented by a small amount of published organ music and a couple of glees.

Lyrics: Anon, probably the composer

Hush, the god of love here sleeping lies,
His hands disarmed, and closed his wanton eyes.
The bow unstrung a while forgets to wound;
His useless shafts lie scattered on the ground.
Sleep on sweet babe, and smiling promise peace,
For should'st thou wake, we know 'twill quickly cease.
