I believe that was the Tribute to Jeff Porcaro concert. Eddie and Luke really ripped it up then and both had awesome tone!
Did you catch the video of EVH at the recent Fender aftershow NAMM party?
He was playing ther new Frnakie Replica - a snip at $25,000 and his new 5150 III amp was also there albeit as a prototype! Looks like its gonna be a great year for EVH/van Halen and Ed appears to have got his tone back (ie no sustainer nonsense)
Here's the link to the Fender gig and also a few others!
Also worthy of mention is the new issue of Guitar World with an 18 minute video on DVD included interviewing Ed and Ghip from the Fender/Charvel/Jackson custom shop discussing the new replica!
