Bruce Springsteen's commitment to veteran causes has been steadfast. The veterans benefit event that gets the biggest boost from The Boss is Stand Up For Heroes, presented annually in the fall in New York City. The 2014 edition bagged the biggest trove of donated items ever from Bruce. The most valuable item? Hang time.  A bidder putting up $300,000 earned a day with Springsteen including a lasagna dinner at Springsteen's home, a private guitar lesson and a ride in the sidecar of Bruce's motorcycle.  Springsteen also donated a couple of guitars to the cause, pushing the total total the programs serving vets will gain past the half million mark.
