His wife was there with his daughters.

Glad they got to share the moment.
At the risk of getting cheesy for a minute:Guy is the ultimate family man... Wife was previously married and 2 of his 3 daughters come from that marriage. About a decade ago I was recording a small solo acoustic coffee-shop style show of his (later self-released at shows) and he starts playing this one track "angels of my home" which he wrote right before the show, musing about what would happen to his young family if he died:
"I can always see the sky here, and my life makes perfect sense - 3 angels I was given, at another man's expense - you gave me reason to believe in me, now I want you to know - You gave me life, now I must go - singing to the angels of my home".
A lot of his original stuff addresses his ongoing struggles with whether music is the right path for him or not. Likely a common theme with many artists I imagine. However, a personal favorite is a "future retrospect" track called
Rock & Roll Hand (download MP3 here). Again, just a very raw "guy and his guitar" track from a decade ago but I love the song (sadly he's never recorded it). IMO that song would go for top dollar in nashville but he refuses to sell it.
He's stepped away from the Mic several times in his life for varying lengths of time... It's always bummed me out when he has. The guy has IT and deserves the break more than anyone I've ever met.
