Fortunately, the person providing the live sound that night was able to capture this performance onto audio cassette tape and share it with others in 2005 on the file sharing site named "Dimeadozen" which allows only previously unreleased live recordings.
The original information file (very lightly edited for clarity) accompanying the reposting of the show in 2016 is as follows:

original uploader's 2005 notes:
--
Ustad Amjad Ali Khan comes from a long line of master musicians in India. He plays the fretless lute, the sarod. He is considered to be one of the top sarod players in India, along with Ustad Ali Akbar Khan and Pandit Buddhadev Das Gupta.
Tabla accompaniment is provided by Abhijit Banerjee,
a disciple of the great Pandit Jnan Prakash Ghosh.
Jnan Ghosh has trained some of India's top tabla players,
including Kanai Datta, Shankar Ghosh, Nikhil Ghosh, Anindo Chatterjee, Samir Chatterjee, and Sanjay Mukherjee.
Amjad was in a good mood that day and in top form. He seemed to have a lot of tuning problems though and I have cut out the fairly extensive tuning segments.
The Bihag Gat starts and almost immediately there was a tape flip and at the same time they started tuning again so it worked out. I just faded it in as they are tuning and they launch immediately into the gat. This is the complete show.
Technical Notes:
I worked the sound for this show and this recording is produced from my master cassette recorded off of the (mono) soundboard.
The level was set a little low so it's a bit hissy in quieter parts but excellent quality and performance. (I prefer lower levels and some hiss to distortion anyway.)
Fine Print:
You may distribute in lossless format only.
You may not sell it under any circumstances
but may trade (or give it away) freely.
source/lineage:
SBD->master cassette->Audiophile 2496->Sound Forge->Flac8-> 2005 seed
reseed:
volume adjustments [to correct clipping]
and a few repairs [clicks] made,
no EQ or other processing applied;
new FLAC-8 files and checksum files created and this info file revised;
original info file included.
Thanks again to the taper and original seeder for this recording.

In respect to the original's taper's wishes, I am not distributing this in lossy formats such as mp3. When such files are then converted to FLAC or WAV, there is a degradation in sound quality which can not be repaired.
This file can be burned to a CD and not lose any sound quality
