Digitized from a shellac record, at 78 revolutions per minute. Four stylii were used to transfer this record.They are 3.5 mil truncated eliptical, 2.3 mil truncated conical, 2.8 mil truncated conical, 3.3 mil truncated conical. These were recorded flat and then also equalized with Turnover: 400.0, Rolloff: -18.0.

The preferred version suggested by an audio engineer at George Blood, L.P. is the equalized version recorded with the 3.5 mil truncated eliptical stylus, and has been copied to have the more friendly filename.
