I've seen the Boss 5 times and his River concert at the LA Sports Arena in 1980, was the single greatest concert I've ever been to.
And I've seen the Stones, the Who, Black Sabbath, Led Zeppelin, Pink Floyd, the Eagles, Deep Purple, Nirvana, Bob Dylan, Jethro Tull, Alice Cooper, J-Geils Band, the Allman Brothers, Moody Blues, Clapton, Beck, Jeff Healy and Olivia Newton John. Well, forget that last one.
