Question: Which musician in Circus Diablo is also the frontman for the Scottish hard rock band The Almighty?
Context: 2XS is the thirteenth studio album by the Scottish hard rock band Nazareth, released in February 1982.  The album includes the rock radio hit "Love Leads To Madness" and the song "Dream On", which has become one of the band's biggest hits and was later covered by Helix. William Daniel "Dan" McCafferty (born 14 October 1946, Dunfermline, Scotland) is a Scottish vocalist, best known as the lead singer for the Scottish hard rock band Nazareth from its founding in 1968 to his retirement from touring with the band in 2013.  McCafferty continues to perform solo around the world and record on occasion. Pete Agnew (born 14 September 1946) is the Scottish bassist and vocalist with the Scottish hard rock band Nazareth.  Born in Dunfermline, Scotland, he is the last founding member still performing with the band, which released its first album "Nazareth" in 1971. Wired Desire is a Scottish hard rock band which was formed in Glasgow in 2005 with their first album in 2008.  They have toured the UK supporting many bands including Wishbone Ash and Nazareth.  Their debut EP, "Barely Illegal", received positive reviews, most notably from Classic Rock Magazine.  Nazareth called Wired Desire, "their best support act ever." Exercises is the second studio album by the Scottish hard rock band Nazareth, released in 1972.  Although their music is most accurately described as "blues-tinged hard rock" (CD liner notes), this record is quite far from the band's more standard fare, featuring, quite surprisingly, a number of acoustic arrangements, several songs with orchestral strings, and traditional Scottish airs.  Indeed, the album's "1692 (Glen Coe Massacre)" is about a real incident in Scottish history, namely, the massacre of Glencoe.  The album is also significant for its Roy Thomas Baker production—only his third project, and well before his breakthrough works with Queen in the mid-seventies—and its oddly 'new wave' cover-art (designed by CCS Associates).  An early version of the Razamanaz song, "Woke Up This Morning", also makes an appearance on Side 1. Circus Diablo is an American rock band, formed in early 2006 by Billy Morrison (vocals), Billy Duffy (lead guitar) and Ricky Warwick (rhythm guitar).  Fuel frontman Brett Scallions and Velvet Revolver drummer Matt Sorum subsequently joined the band on bass and drums, respectively.  To date, Circus Diablo have released one studio album, entitled "Circus Diablo". The Almighty are a hard rock/heavy metal band, from Glasgow in Scotland who formed in 1988.  Three of the founding members, Ricky Warwick, Stump Monroe and Floyd London were friends who met at school.  Although the band members musical roots were in punk, The Almighty adopted a more heavy metal/hard rock oriented musical direction in their early years.  Later albums saw the band's musical style move towards the band members' original punk roots. Billy Morrison is an English guitarist, singer and actor who plays guitar with Billy Idol and performs with the Los Angeles-based cover band Royal Machines (and previously with Camp Freddy).  Morrison previously fronted the hard rock act Circus Diablo and has been a member of The Cult, Stimulator, Doheny and Into a Circle. Razamanaz is the third studio album by the Scottish hard rock band Nazareth, released in 1973.  It was the band's first LP record to break the charts and was produced by Deep Purple's Roger Glover who the band was on tour with at the time.  "Woke Up This Morning" was re-recorded for this album. Ricky Warwick (born 11 July 1966, Newtownards, County Down, Northern Ireland) is a Northern Irish musician and songwriter, and the lead singer with Black Star Riders and Thin Lizzy.  He is also the frontman for the Scottish hard rock band The Almighty, with whom he achieved chart success in the UK throughout the 1990s, although the band is currently on hiatus.  Warwick has released several solo albums and performed with a variety of other bands and artists, and also fronts his own band, The Fighting Hearts, to showcase his solo material.
