Three adjectives that describe you: Irish, spaz, and needy.
Favorite activities: Hanging with my kids, playing guitar, and running.
What do you think will be the most difficult part of living inside the Big Brother house?
Being away from my family, no doubt. Also, trying to sleep without earbuds because of my tinnitus, better known as ringing in my ears.
What moment in your career do you think prepared you to live in the Big Brother house?
Being in a band on tour with some erratic personalities, in the small confines of a tour bus, for months at a time... for the last 25 years!
Which past Big Brother cast member did you like most?
Of course the legends, Boogie and Evel Dick… but BB19 was strong with Cody and Jessica, and of course, bringing Paul back. But my favorite ever was the Beantown legend and fellow hair streaker, Kevin… love that guy!
Do you have a strategy for winning the game?
Since this is a truncated, expedited version of the game, playing the wall might not be the best strategy. Hearts are gonna be broken early and there's nowhere to hide. So I figure you might as well come in hot!
My life's motto is…
"Just be nice." - Dalton Lee from the classic movie Roadhouse.
What would you take into the house and why?
Guitar. I might as well write a few songs while I'm there since I'm sure there'll be a ton of inspiration!
Fun facts about yourself:
- Three-time Rock & Roll Jeopardy! champion.
- Once shot a half-court shot at a Laker game at halftime for $50,000 with Jack Nicholson watching… I missed badly.
- Proud USC alumni.
