The Shannon Quartet had previously recorded "Sidewalks of New York" in April 1924 on Victor 19336. The rendition posted above, recorded just two years later in June 1926, makes this one of a number of songs that Victor rerecorded in the early days of the Orthophonic era. "Sidewalks of New York" certainly had longevity, as recordings of the song date back to the 90s.
It is relevant to note that "Maggie Murphy's Home" appeared on the flip side of both the acoustic and the electric renditions.
