I saw him twice and 1990, and I have to say he colored it alot more then than in 1993. It looked very dark in person. On "Get back", the light sometimes makes it look like it was grey.
And..I did a "Band on the Run" 3 way video comparison last night....1976-1990-2002. His voice was pretty darn strong in 1976, but he wasnt as spot on on his timing. 1990 just plase in comparison. 2002 was best timing and a bit weaker than 1976, but SOOO much better than 1990. As for the band...1976---grossly over-rated. 1990---played WAY too slow. 2002---damn near perfection. Yes--I know--I have no life, lol. Check it out though,,,,,
