Brought to you by possibly the only person on the planet not sick of Pachelbel's Canon - ME!
This is probably my favorite performance of the traditional arrangement:
My favorite more modern arrangement is New Age Orchestra's Classical guitar version. It is not on Youtube.
Canon fans may be aware of JerryC's arrangement, Canon Rock, used by many Youtubers as the musical landscape for their Canon fantasies, or as inspiration for their own arrangements.
For the guitar fans:
What was that? Oh, one guitar isn't enough for you? Oookaaay...
Huh? Do I have a version played by 75 musicians?? Are you ins-- Well, actually, yes, I do. Heh.
Oh, sorry. You have a headache now? Here, have some Anacin!
