It would be interesting to see the results of that comparison Bob.

I'm also interested in seeing how merely changing the tempo of a song affects it reception/perception. (remember for example Mona Lisa sung by Nat King Cole, and the rock n roll version by Shakin Stevens (UK)?) I'm used to hearing thr Last Leviathon performed at a reasonable pace, then at Whitby heard 'catter Willa sing it beatifully slowly and it has changed my whole perception of that grate Andy Burns song.
