Question: Are Dolores O'Riordan and Gerry Marsden both lead singers of a band?
Context: "Zombie" is a protest song by Irish rock band The Cranberries.  It was released in September 1994 as the lead single from their second studio album, "No Need to Argue" (1994).  The song was written by the band's lead singer Dolores O'Riordan, and reached No. 1 on the charts in Australia, Belgium, France, Denmark and Germany. Dolores Mary Eileen O'Riordan ( ; born 6 September 1971) is an Irish musician and singer-songwriter.  She led the rock band The Cranberries to worldwide success for thirteen years before the band took a break starting in 2003, reuniting in 2009. The 1989 FA Cup Final was the final of the 1988–89 FA Cup, the top football knockout competition in England.  The match was a Merseyside derby between Liverpool and Everton, played at Wembley Stadium, London, on 20 May 1989.  Liverpool won 3–2 after extra time, with goals from John Aldridge and two from Ian Rush.  Stuart McCall scored both Everton goals.  The final was played only five weeks after the Hillsborough disaster, in which 96 Liverpool fans were killed in a crush, and before kick-off there was a minute's silence and the teams wore black armbands as a sign of respect.  Gerry Marsden, lead singer of Gerry & the Pacemakers, led the crowd in a rendition of his hit "You'll Never Walk Alone", which had become synonymous with Liverpool Football Club. "Ferry Cross the Mersey" (sometimes written Ferry 'Cross the Mersey) is a song written by Gerry Marsden.  It was first recorded by his band Gerry and the Pacemakers and released in late 1964 in the UK and in 1965 in the United States.  It was a hit on both sides of the Atlantic, reaching number six in the United States and number eight in the UK.  The song is from the film of the same name and was released on its soundtrack album.  In the mid-1990s a musical theatre production also titled "Ferry Cross the Mersey" related Gerry Marsden's Merseybeat days; it premiered in Liverpool and played in the UK, Australia, and Canada. "Don't Let the Sun Catch You Crying" is a song written and originally performed by British beat group Gerry and the Pacemakers.  The songwriting is credited to Gerry Marsden and the other band members, Freddie Marsden, Les Chadwick and Les Maguire.  It was first recorded by Louise Cordet, and then recorded by the group themselves in early 1964. Gerard Marsden MBE (born 24 September 1942) is an English musician and television personality, best known for being leader of the British Merseybeat band Gerry and the Pacemakers. "I Like It" is the second single by Liverpudlian band Gerry and the Pacemakers.  Like Gerry Marsden's first number one, it was written by Mitch Murray.  The song reached number one in the UK Singles Chart on 20 June 1963, where it stayed for four weeks.  It reached No. 17 in the American charts in 1964. "Hollywood" is a rock song by Irish band The Cranberries.  It is the fourth single from the band's third album, entitled "To The Faithful Departed".  Plans to record a video clip were abandoned after the band cancelled the remaining of their Free to Decide World Tour and other promotional activities due to lead singer Dolores O'Riordan's health problems.  The worldwide release of a commercial CD single was cancelled as well, except in France. Water Circle is the second demo EP of the Irish band The Cranberry Saw Us.  It was released in cassette format and was used as an unsolicited demo sent to various major record labels.  This is the first release to feature the vocal stylings of Dolores O'Riordan.  All songs on the EP are written by Dolores O'Riordan and Noel Hogan.  A bootleg MP3 of Water Circle appeared on the internet in 2002 courtesy of The Cranberries' drummer Fergal Lawler, who gave two CD-Rs of rare tracks to Alex Kraus, owner of the now closed fan site www.zomebieguide.com.  The actual cassette EP has been for sale via eBay for some time now, due in part to the asking price of US$1499.95.  It is the only copy known to still exist and is owned by Mr Kraus. No Need to Argue is the second studio album by the Irish rock band The Cranberries, released on 3 October 1994.  It is the band's best selling album, and has sold about 17 million copies worldwide.  It contains the band's most successful single to date, "Zombie".  The album's mood is darker and harsher than that on "Everybody Else Is Doing It, So Why Can't We? ", released a year before.  It shows a more mature performance by lead singer Dolores O'Riordan, writing about war, death, love and disappointment.  Her voice is clearer, without the previous album's double and triple voice layering.
