Question: Are both Holly Johnson and Joe Lynn Turner musicians?

<P0-S0> Fire Without Flame is a hard rock album by Akira Kajiyama and Joe Lynn Turner. <P0-S1>  This is the first release under both their names. <P0-S2>  "Fire Without Flame" is more of a return to "Slam" era sensibilities: a blistering blues infused hard rock album, on which Kajiyama handled all instruments and production himself. <P0-S3>  While absent of song writing credits, it’s assumed that Turner contributed all lyrics and vocal melodies. <SEP> <P1-S0> Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) are a British rock band led by guitarist Ritchie Blackmore, active from 1975 to 1984, from 1993 to 1997, and from 2015 to the present. <P1-S1>  They were originally established with Ronnie James Dio's American rock band Elf, but after their first album, Blackmore fired the backing members and continued with Dio until 1979. <P1-S2>  Three British musicians joined in 1979, singer Graham Bonnet, keyboardist Don Airey, former Deep Purple bassist Roger Glover, and this line-up gave the band their commercial breakthrough with the single "Since You Been Gone". <P1-S3>  Over the years Rainbow went through many line-up changes with no two studio albums featuring the same line-up. <P1-S4>  Other lead singers Joe Lynn Turner and Doogie White would follow, and the project consisted of numerous backing musicians. <P1-S5>  A pioneer to power metal, the band's early work primarily featured mystical lyrics with a neoclassical metal style, but went in a more streamlined, commercial direction following Dio's departure from the group. <SEP> <P2-S0>  He is known for his work in the hard rock bands Rainbow and Deep Purple. <P2-S1>  During his career, Turner fronted and played guitar with pop rock band Fandango in the late 1970s; and in the early 80s, he became a member of Rainbow, fronting the band and writing songs with guitarist, Ritchie Blackmore and bassist, and producer, Roger Glover. <P2-S2>  After Rainbow had disbanded (the first time) in March 1984, he pursued a solo career, released one album, Rescue You, and then later did session work, singing background vocals for the likes of Billy Joel, Cher, and Michael Bolton. <P2-S3>  On the advice of Bolton, Turner began recording jingles for radio and television. <P2-S4>  Other songs he had composed or through collaboration with songwriters like Desmond Child and Jack Ponti were being recorded and released by international recording artists Jimmy Barnes, Lee Aaron, and Bonfire. <P2-S5>  Turner had a short-lived association with neoclassical metal guitarist Yngwie Malmsteen and then Deep Purple. <P2-S6>  From the mid-1990s, he resumed his solo career, releasing an additional nine studio and two live recordings. <P2-S7>  Turner did other session work, appearing as lead vocalist on tribute albums and working on projects involving various musical groups including progressive rock band Mother's Army; Bulgarian hard rock band Brazen Abbot; funk rock duo Hughes Turner Project; and classic rock/ progressive rock band Rated X. <P2-S8>  In 2006, Frontiers Records approached Turner to become involved with the AOR side project Sunstorm. <P2-S9>  By 2016, four albums under the Sunstorm name had been released. <P2-S10> Joe Lynn Turner (born Joseph Arthur Mark Linquito, August 2, 1951) is an American singer, guitarist, songwriter, and producer. <P2-S11>  That same year, Turner released "The Sessions" via Cleopatra Records featuring a veritable who's who of classic rock royalty as guest musicians, before resuming his seemingly constant touring schedule back in Europe <SEP> <P3-S0>  Prior to that, in the late 1970s he was a bassist for the band Big in Japan. <P3-S1>  In 1989, Johnson's debut solo album, "Blast", reached number one in the UK albums chart. <P3-S2>  Two singles from the album – "Love Train" and "Americanos" – reached the top 5 of the UK Singles Chart. <P3-S3>  In the 1990s he embarked on a painting career. <P3-S4> William Holly Johnson (born 9 February 1960), born William Johnson and known professionally as Holly Johnson, is an English artist, musician and writer, best known as the lead vocalist of Frankie Goes to Hollywood, who achieved huge commercial success in the mid-1980s.
