TEXXAS JAM 1979 #1 1979 (June 9) - Texxas Music Festival, Cotton Bowl, Dallas, Texas (General Admission - $15.00) TKO Sammy Hagar Nazareth Van Halen Boston Heart Blue Öyster Cult Notes: The order of appearance on this bill was TKO/Hagar/Nazareth/Van Halen/Boston/Heart/BOC. Blue Oyster Cult headlined this show. TKO was managed by the same management as Heart at the time, which is the reason for their appearance on the bill. KTXQ-FM Q-102 simulcast much of this concert throughout the day, with TKO, Hagar, Nazareth, and portions of Heart's show aired live. Van Halen's set was not broadcast, and KTXQ had to unplug their sound equipment for Boston's set, which they did before Heart took the stage. As a result, only a portion of Heart's set was aired, the sound being broadcast from microphones placed around the Cotton Bowl.
