Sub-Rosa Subway

"Sub-Rosa Subway" was written by Woloschuk and Dino Tome and runs 4:34 on 3:47 EST, with Vern Dorge on chimes; the spelling also appears without hyphens. An earlier version was the B-side of the 1973 GRT single "Anus of Uranus", credited to Chip Dale, Tome's pseudonym. The album version was the B-side of the 1976 single "Calling Occupants of Interplanetary Craft", and the double-sided single peaked at number 62 in the US, the band's only US chart entry.

The subject is Alfred Ely Beach's pneumatic subway under Broadway in New York, which Wikipedia's Beach article says the 1976 Klaatu single is about. The line ran from February 1870 to April 1873. Beach opened it to the public on February 26, 1870, about 300 feet long and under Broadway, with a station in the basement of Devlin's clothing store at Broadway and Warren Street. He spent $350,000 of his own money plus $70,000 on a luxurious station, and built it at night in secret to avoid Boss Tweed, finishing the tunnel in 58 nights. Search results suggest a podcast about Matthew Algeo's book on Beach uses the song as its theme and that blogs read it as alluding to the station's goldfish fountain, but we did not fetch those pages.

Setlist.fm lists it as the third most played Klaatu song with 11 performances in 25 logged setlists, 10 of them in 1981. We found no song-level recording date or studio, and no covers or samples.
