i played bard to 51 on live, but have very vague memory of this song
the description here http://wiki.project1999.org/index.php/Bard says its AE mez, but description inside states single target
i thought it was aoe lull

Classically, its an AoE Mezz with a 1tick duration. Eventually it was changed on Live to a single target, 3 tick duration, matching the bard's other mez songs.

Since this server is Classic, its a 1tick AoE mez. Just really hard to land on higher level targets.
