Gregmark Records was founded by Lester Sill in 1961, a year before he started Philles Records with Phil Spector.
The Paris Sisters recorded five singles for the label, two of them produced by Spector. "Caravan" is a Gregmark recording attributed to Duane Eddy, but in fact is by the session man, Al Casey.
