Question: What are the names of the brothers who form the band behind the Flick of the Switch/Monsters of Rock Tour?
Context: Live at Monsters of Rock is a live album and DVD Northern Irish blues guitarist and singer Gary Moore.  It was recorded live on May 21, 2003 at Sheffield Hallam Arena in England, during Gary Moore's appearances on the 2003 Monsters of Rock tour. The Monsters of Rock Tour 1988 was a festival tour headlined by hard rock band Van Halen as part of their promotion for their "OU812" album.  The Scorpions were a co-headliner.  Opening bands included Metallica, Dokken, and Kingdom Come.  It formed the first section of the OU812 Tour, the main part of which followed immediately after Monsters of Rock 1988.  As one of the many well known Monsters of Rock tours, the tour featured an impressive line-up, especially for a single day event, and proved very popular. Monsters of Rock Tour 1987 was the festival tour of Europe by the American thrash metal band Metallica.  It was the second time Metallica attended Monsters of Rock. AC/DC are an Australian hard rock band, formed in Sydney in 1973 by brothers Malcolm and Angus Young.  A hard rock/blues rock band, they have also been considered a heavy metal band, although they have always dubbed their music simply "rock and roll". Flick of the Switch is the ninth studio album by Australian hard rock band AC/DC.  Released in 1983, it followed the highly successful "Back in Black" and "For Those About to Rock" albums.  "Flick of the Switch" is the third AC/DC album to feature lead vocalist Brian Johnson, and last to feature drummer Phil Rudd before his eleven-year break from the band.  It is the band's eighth internationally released studio album, the ninth to be released in their native Australia.  All songs on the album were composed by guitarists Malcolm and Angus Young and vocalist Johnson. The Monsters of Rock Tour 1984 was a festival tour of Europe in 1984.  The lineup for the then-annual Monsters of Rock festival in Donington, England took the festival out on tour.  For a short portion of the tour, hard rock band Van Halen played on the bill as the brief European leg of their 1984 Tour supporting the album of the same name.  It was the second portion of the tour after a large North American one and featured the final performances by David Lee Roth with the band until he rejoined in 2007.  Raised tensions may explain why they left the bill before the tour's end. The OU812 Tour was a concert tour by hard rock band Van Halen.  It was the second tour to include dates in Japan, and was the second with Sammy Hagar as vocalist (who had settled into the role more by this point).  It followed the Monsters of Rock Tour 1988, which had formed the first part of the promotion for the "OU812" album. Guitar Rock Tour 2 is a music video game developed and published by Gameloft for the iOS, Symbian and Nintendo.  It was released on July 9, 2009, as the sequel to 2008's "Guitar Rock Tour" from the same developer. The Flick of the Switch/Monsters of Rock Tour was a concert tour by the Australian rock band AC/DC in support of their released album Flick of the Switch in 1983. The 1984 Tour was a North American concert tour by hard rock band Van Halen in support of their album "1984".  The tour was very successful but tension between the Van Halen brothers and Roth was high.  After the tour, the band continued to promote the album on their Monsters of Rock Tour 1984 (a short European festival tour to compensate for the main "1984 Tour" being North American only), and then David Lee Roth left Van Halen.  He would not perform live with them until the 2007 reunion tour.  The tour was one of the band's longer ones, but was divided into four separate legs.  American glam metal band Autograph was an opening act for the tour.
