Joan Baez sang it at Woodstock - Arlo might have, as well, but it's not on any list I've seen or heard.

"Silver Taps was played with one bugle near the gravesite and the other some distance removed so the effect was that of an echo"

That's probably why it sounds bad on TV - the whole distance thing is messed up because they have mics close by both buglers (though I can't remember when I actually heard is played on a bugle - just coronets & trumpets).
