How rare is Four Songs? Options

[torcatofan]

So I went into a local cd/dvd store today just to look around. Turns out they had a few used Live cds there. But until then I had never seen a Four Songs cd. So of course I bought it for a very reasonable $5. I know that the Four Songs cassettes are pretty rare, but I was wondering how rare the cds are. This has a copyright 1991 so I'm assuming it was printed before Live became well-known. Anyone have an idea?

I have a promo copy of 'Four Songs.' It has one of those "This compact disc is the property of applicable record label...yada yada yada...Resale is unlawful and may be punishable by applicable laws" stickers slapped onto the front. Not sure if it's rare though, and I'm not sure if any other aspect of the disc or inserts differs from the non-promo disc.
