Haneros Halalu

Did you ever wonder why the niggun "Haneros Halalu" is so drawn out?

The reason for this is that the Rebbe Maharash was not well, so he wasn't in public to often. One of the only times the Rebbe Maharash came out, was by the Menorah Lighting. So the Chasidim came up with a brilliant idea, so they stretch Haneros Halalu as long as possible, in order to see the Rebbe longer.
