I am choosing to ignore the infantile blatherings from down under (which is where the right dishonourable "gentleman" should be... preferably at least six feet down to avoid any residual odours from poluting the atmosphere of the purer Northern Hemisphere) (that was a none too subtle reference to the most famous book by my favourite author, Nevil Shute:
his "On The Beach" postulated that after a world nuclear war Melbourne would be the location of the end of mankind a chilling thought).
Instead I will concentrate on this understanding/misunderstanding business because it now appears that I correctly identified young Peter K as being MrGoldMind123 and that he did indeed create those "videos" and was the sole uploader of them (there was no "somebody else"), what surprises me again is that the downloaded audio file from sugarmegs sounds a heck of a lot better than it has any logical right to
(geek speak interlude go and twiddle your thumbs or something Char)
If you download the sound file using the download link from sugarmegs
(which is to:-
http://www.archive.org/serve/GordonL...1987-09-13.wma )
you get a relatively smallish 43 minute long 12.4MB file named
GordonLightfoot1987-09-13.wma where the wma file extension indicates that it is a Windows Media Audio format file.
If you then were to be so bold as to analyse it with the most excellent free utility mediainfo from:-
http://mediainfo.sourceforge.net/en
you will see the results as in the screenshot that I will be attaching
 
note that with all audio files their file size is directly proportional to what is somewhat oddly named the "sampling rate" which is measured in bits per second or in other words the "bit rate" and the units are commonly referred to as KBPS for KiloBits Per Second
If you are unfamiliar with this there is of course the inevitable wiki at:-
http://en.wikipedia.org/wiki/Bit_rate
so as you can see from the screenshot this wma file is encoded at the distinctly low rate of only 40 KBPS
by comparison on that wiki is a listing of various mp3 bitrates at
http://en.wikipedia.org/wiki/Bit_rate#MP3
including
96 kbit/s - generally used for speech or low-quality streaming
and
128 or 160 kbit/s – low-to-standard bitrate quality; difference can sometimes be obvious
192 kbit/s - a commonly used high-quality bitrate
320 kbit/s - highest level supported by MP3 standard
if you check the wma wiki you can read
"Microsoft also claimed that WMA delivered "near CD-quality" audio at 64 kbit/s"
also
"Microsoft claims that audio encoded with WMA sounds better than MP3 at the same bit rate"
and
"Microsoft has sometimes claimed that the sound quality of WMA at 64 kbit/s equals or exceeds that of MP3 at 128 kbit/s"
despite that as we all know it is mp3 that has become the universal standard for distributing music files
Andy T's erudite report on his own experiments at
http://www.corfid.com/vbb/showpost.p...0&postcount=11
stated:-
"Usually over 144kbs in stereo I found eliminated most of that "treble warble" you get from compression,128 isn't bad either, but you can tell it's an MP3 more easily. So I tend to just go with an average bitrate of 144 or 160, sometimes 128 if the track is not as important"
Personally I use the better 192 value.
Of course both mp3 and wma formats are "lossy" therefore reconstituting a CD from them can never replicate the full sound spectrum which means that purists and audiophiles (where is the long AWOL Sydneysider Gunter? the more acceptable (less ugly) face of Oz) insist on lossless compression such as FLAC (Free Lossless Audio Codec)
due to that in fact the prime audio bootleg torent listing website, dimeadozen. bans mp3s completely (there is a torrent for the Folkfest flac set showing but at the moment there are no seeders)
For comparison CD standard files are in the PCM format and their audio bitrate is 1,411.2 Kbit/s
OK end of my little geek speak section you can come out of hiding now Char
The other point discussed was the date of the recording: as I revealed in the downloaded filename and as recorded on Wayne's 1987 Tour Dates page the date was Septembe 13th.
I checked Wayne's Radio Appearances page and found that on March 8,1987 Gord was interviewed byPete Fornatale (whose name Wayne also mispelt as Fornatel). to confuse matters on both dates Gord performed Madam Charlene's Signature song ITA.
