Brwn_eyes0511 told me about MegaUpload & I think it's worked, for those of you wanting to save the MS73 file, here it is in it's entirety:

...well, it's not complete really as I don't have the Chuck Berry intro but both full tracks are there. Thanks Brown Eyes!
It's 213 MB in size & took me 2 hours to process but a friend of mine tried it and said it only took them 30 minutes on their end.
