Hi! Billy Weeks. Do you mean "Hop Lite Loo"?
The comedian's name should be Frank Lum, not Lunn, my mistake.

My 1860s? date is based on the images on the border of this Masran (NY) sheet, and the address, No. 54, Chatham St. It could have appeared in earlier printings, and certainly the song was an 'Ethiopian' hit from 1843 onwards. No certain knowledge about the time Masran occupied those premises, but somewhere I saw the date 1850s-1860s.

Also on the sheet is the fake Irish "Little Pigs," which, with the line "Lilipulari, my dad was a bonny wee man," suggests "Lilibularo."

I will try to find out when 'Frank Lum' was active, but it is not easy to track these old minstrels down.

Rex, 'Get out de way' does seem to be the earliest- on the 1843 sheet music credited to James M. Deems and others.
