It is a great ‘semi-official’ bootleg recording. It is hard to find at times but you can usually find it on http://www.gemm.com (which is a HUGE collection of independent record stores)
* one seller currently has it for $11.69. I love that place 
ps – if any of you know owners of mom + pop record shops or own one yourself, you should consider extending your sales into that site. Even if you have an online store already. I hate seeing so many of these places dying. We just lost Repo Records in Charlotte and just barely kept Manifest Records (thanks to new owners).
