This was released by FSM in an expanded edition in 2005 along with Roy Budd's The Carey Treatment and Goldsmith's Coma (

I have significant doubts that this expansion will ever be re-released on CD, but stranger things have happened. In the meantime, search the Amazon Marketplace and eBay every now and then to see if you can get a used copy for a decent price.
