The organ was discarded several years ago. Console removed. Eletronic substitute installed. The organist reports there are some pipes still behind the facade.

Instrument was removed by Grafton Organ Company and replaced with a Allen in the early 2000's. Nothing remains but the facade.

Built by C. S. Haskell c.1897, with tubular- or electro-pneumatic action to slider chests, it is housed in a chamber located over the sacristy. It is listed by Haskell as a three-manual instrument; perhaps the firm considered it as "prepared for" the addition of a choir or solo division. There is certainly room for the addition of another division in the huge chamber, which is the size of a small railway station. The organ was provided with a replacement console by Edgar H. Mangam of Philadelphia around 1976, but is tonally unaltered.

The Great is on two massive chests, and has two prepared-for stops. The Swell, on one chest of truly heroic proportions, has four prepared-for stops. The Stopped Diapason 8' has pierced stoppers; the Dolce Celeste 8' has an octave of capped basses; the "Gemshom" 4' is not tapered and is actually a principal; the Cornopean is not harmonic.

The congregation was known as St. Ansrew's from 1851-1965 when they merged with St. Monica's to become The Church of St. Andrew and Monica.

A 1910 ad in The Philadelphia Inquirer lists an organ installed here by Bates & Culley. This project was likely a rebuild or repair to the Haskell organ.

Built by Charles S. Haskell, and appeared on an opus list published by the firm in The Diapason, January, 1909.
