I was sure it was bullshit too, maybe torrents, maybe official live, but the Gaslight thing is new to me too. I hoped to spur some discussion and speculation.
From a quickie Google search I found the following- could possibly be...
The Gaslight Cafe
116 MacDougal Street
New York City, New York
The Gaslight Cafe was an American coffee house located in the basement of 116 MacDougal Street in the Greenwich Village neighborhood of the Manhattan borough of New York City, New York. The Gaslight (alternatively known as "The Village Gaslight" opened in 1958 and was a well known venue for folk music and other musical acts, until it closed in 1971.
...Also next door was the Folklore Center, a bookstore/record store owned by Izzy Young and notable for being a musicians' gathering place and center of the New York folk-music scene. Live at The Gaslight 1962 (2005), a single CD release including ten songs from early Dylan performances at the club, was released by Columbia Records... Maybe the "Gaslight" is Dylan? I wouldn't think this reel sells for much without more details.
