Previously listed as dating to the band's May 1969 US tour, the release of the Ludlow Garage 40th Anniversary compilation by Shake It Records confirms the date as either the 28th or 29th of November 1969. This compilation includes 'This Moment' by the ISB, although it is not known whether this is the same version as it may be from the other date. According to this/a "CityBeat" article, almost all concerts at the venue were recorded, so other tapes may still exist.
