There was actually a registered ship named the SS Virginian which was built in 1904 and scrapped around 1954. The ship had one funnel with the Allan Liner's colors on it. The SS Virginian also had a vital part in the Titanic disaster in April 1912 as she was reported near the vicinity of the sinking and within radio contact.
Exterior shots of the ship are the inspired blueprints of the SS Lusitania and her sister ship the SS Mauritania. The ballroom in which 1900 plays his piano in had a dome similar to the dome the SS Mauritania had in her ballroom during the transatlantic period.

The recording equipment used for making the record was clearly acoustic in nature, showing large horns. This type of recording was largely replaced in 1925 by electrical recording, using microphones. Yet the recording was made somewhere between 1927 and 1933, according to Tooney's story. Furthermore, the recording engineer played back the matrix immediately; this would have ruined the matrix, which was cut in wax. In those days, immediate playback was only possible using a 2nd set of equipment expressly for that purpose.
