bigjohn,
Good idea. I got home in time to watch an hour or so of the show, and it certainly looked spectacular in HD. I'd never heard John Mayer before--only seen posters of him in my local Towers store. While a bit on the bland side of the ledger, he is an excellent guitar player and singer.
And while I applaud the tribute to the late, great Ray Charles, it's a shame that only a couple of cuts on that Genius Loves Company album are really good, mainly the duet with the great Bonnie Rait.
Regards,
