• Styx (Kilroy Was Here tour)
• Sammy Hagar
• Triumph
• Ted Nugent
• Uriah Heep

Sammy came on right before Styx at the end. Trivia: Ted Nugent and Rik Emmett joined Sammy Hagar on stage in Dallas for their version of Led Zeppelin's "Rock "n Roll." Tommy Shaw recalls these shows as being some of the worst of his career. He claims to have feared for his life as his band was performing nothing but the (lame)ROCK OPERA "Killroy was here" after some of the best hard rock bands of the day had performed. (This was the tour that essentially ended Styx.) Not even RENEGADE?

That would have been totally awesome. 

Folksong '59.  Featuring Muddy Waters, Memphis Slim, The Cadillacs, Jimmy Driftwood, The Selah Jubilee Singers, Pete Seeger, Mike Seeger, and the hit of the evening, Earl Taylor and the Stoney Mountain Boys (from Bawlmer, Hon!)

Curtis turned to banjo player Walter Hensley and said, "Walt, I don't think they'll like us a bit." Walt recalls that his legs "were like Jell-O - and we had to play the fastest song we knew." But when Walt, with legs shaking, stepped out onto the stage before the assembled audience at Alan Lomax's Folksong '59 concert, Curtis recalls that "he played something on the banjo, and they tore that place up." Curtis Cody wasn't alone in his assessment of the band's performance and the crowd's reaction. "There is true folk magic in every note Walt plays," according to Alan Lomax. Neil V. Rosenberg, in his book Bluegrass: A History, reports that "all agreed that of the various groups in the concert, Earl Taylor and the Stoney Mountain Boys were the hit of the evening." Years later in an article in Bluegrass Unlimited by Tom Ewing, Earl Taylor recalled, "When we would end a number, I knew that it would take five minutes before we could go into another one - that was how much rarin' and screamin' and hair-pullin' there was". The recording of that concert, released as an LP later that year on United Artists (Folksong Festival at Carnegie Hall, UAL 3049), influenced a generation of young musicians and new fans, many from urban areas in the North who were exposed to bluegrass for the first time
