Re: Deep Purple
Given the length of time Voyager has been going I assume we're talking about the 15 minute live verison of Space Trucking (complete with a ~5 minute drum and organ section in the middle while, I assume, the rest of the band sloped off for a backstsage fag!).
N.b. 35 years ago as part of my maths degree at Oxford I did an option on Error Correcting Codes - even then the lecturer said he was astonished NASA could still talk to Voyager given how far away it was!
