Original Ramones 1978 Mediasound NYC studio tapes from 1977 It's Alive UK gig

Here is a pair of original Ramones studio tapes from 1978 that I picked up in a large sale of World music here in the UK. I'm a Ramones nut and as soon as I saw them I thought they must be from the 1977/79 It's Alive gig/album and I was right.
