Question: Which singer was from a rock group, Yannis Philippakis or Limahl?
Context: Foals are an English indie rock band from Oxford, England formed in 2005, consisting of lead vocalist and lead guitarist Yannis Philippakis, drummer and percussionist Jack Bevan, rhythm guitarist Jimmy Smith, bassist Walter Gervers, and keyboardist Edwin Congreave.  Since the band's formation, their line-up has remained constant, except for the departure of former lead singer Andrew Mears. Yannis Philippakis (born 23 April 1986) is the lead singer and guitarist of the British indie rock band Foals. Islands is the second album by the British pop band Kajagoogoo, released on 21 May 1984 on the EMI label.  This was the band's first album without lead vocalist Limahl; who had been fired by the band in mid-1983 and went on to pursue a solo career.  Bass player Nick Beggs, already the group's main backing singer, took over lead vocal duties, and also wrote the lyrics.  The album was co-produced by the band themselves, now a four-piece group, along with Colin Thurston, who had also produced their debut, "White Feathers".  It is the final album to-date to feature founding drummer Jez Strode. "Only For Love" is the debut single by former Kajagoogoo singer Limahl, following being fired from the group by his bandmates in 1983.  The song was featured in the first UK version of "Now That's What I Call Music", and later included on Limahl's 1984 debut solo album, "Don't Suppose".  The song became his first UK Top 20 hit, peaking at No. 16 on the UK Singles Chart.  It remains his second most popular single in the UK as a solo act (the first being "The Neverending Story"). Vincent James "Vince" Lovegrove (19 March 194724 March 2012) was an Australian journalist, music manager, television producer, AIDS awareness pioneer and musician.  He was a member of 1960s rock 'n' roll band The Valentines, sharing vocals with Bon Scott whom he later introduced to heavy rock group AC/DC.  As a journalist, he wrote for Australia's teen music newspaper "Go-Set" from 1971, and was based in London for "Immedia!"  from 1994 for over eight years.  As a manager, his former clients include pub rock singer Jimmy Barnes and rock group Divinyls. Christopher Hamill (born 19 December 1958), better known by his stage name Limahl (an anagram of Hamill), is an English pop singer.  He rose to fame as the lead singer of the 1980s pop group Kajagoogoo, before embarking on a briefly successful solo career, which reached its peak with the 1984 hit "The NeverEnding Story", the theme song for the film of the same name. "Hummer" is the second single by Foals and is the first single with Yannis Philippakis on lead vocals (the previous lead vocalist was Andrew Mears).  It was released on 12 March 2007.  It was recorded and mixed by producer Gareth Parton at the Fortress and Metropolis recording studios, London.  It was released as a digital download and on vinyl on 23 April 2007. Love Is Blind was first released in 1992 (on Bellaphon music label in Germany, and on Jimco label in Japan, the only two countries where the record was ever marketed), and was the third studio album by pop rock/dance singer Limahl.  The work was also released in other two German-speaking countries of central Europe, namely Austria and Switzerland. The Edmund Fitzgerald (formerly known as Elizabeth) were a math rock band from Oxford, England, who disbanded in 2005.  Their final line-up consisted of Yannis Philippakis on lead guitar and vocals, Lina Simon on rhythm guitar, and Jack Bevan on drums.  Philippakis and Bevan later went on to join Foals. What Went Down is the fourth studio album by British rock band Foals, released on 28 August 2015 via Transgressive Records in the United Kingdom.  The album is produced by James Ford, known for his work with Simian Mobile Disco, The Last Shadow Puppets and Arctic Monkeys amongst others.  According to frontman Yannis Philippakis, it is slated to be their loudest and heaviest record to date.  "What Went Down" debuted at #3 on the UK Albums Chart and at #58 on the Billboard 200, making it their highest charting album in the United States to date.
