Question: Who is older, Vincent Walker or David Usher?

full_context: Document 1: Vincent Walker: Vincent Francis Walker (born March 2, 1980), better known as Vince Walker, is an American multi-instrumentalist, best known as the lead singer of third-wave ska band Suburban Legends. He was formerly the lead trumpet player, and left sometime after the release of "Rump Shaker", but returned to the band in September 2005 for the band's appearance on the Jerry Lewis MDA Telethon, which happened to be lead singer Tim Maurer's last performance. He replaced Maurer as the singer in an odd switching of roles, and continues with the band as frontman.
Document 2: Suburban Legends (Tim Remix): After the departure of lead singer Chris Batstone, Suburban Legends re-released their first EP, "Suburban Legends", by removing the vocal track featuring Chris, and replacing it with a vocal track of new lead singer, Tim Maurer. Suburban Legends (Tim Remix) is essentially the same album from the Orange County based ska punk band. It was first released in 2002 in Los Angeles, California by We the People Records. Its first pressing came with a green cover which was later changed to an orange cover. The green cover version is now very hard to find. The music, however, is the same on both editions. The main difference between the two versions is that the green cover edition was released by We the People Records, while the orange cover edition was self-released by the band at the end of the year. As of 2012, both versions are out of print.
Document 3: Hezekiah Usher: Usher was born in 1615. The medieval records known as the Hundred Rolls show that Usher came from the then hamlet of Bednall Green, today's Bethnal Green in East London in England. The Usher family line itself is believed to be originally from the town of Bednall Green. The Usher family name is known in English history and literally means "one who introduced strangers." Usher and his brother Robert left Bednall Green (aka Bethnal Green) and settled in the thirteen colonies. Usher came first to Cambridge.
Document 4: Suburban Legends (Raw): After the departure of lead singer Chris Batstone, Suburban Legends re-released their debut album, Suburban Legends, without the vocal track featuring Chris. This karaoke version of the EP Suburban Legends is essentially the same album from the Orange County based third wave ska band. It was released in 2002, but was only available for download on their MP3.com site, which is no longer available. It has since been released as a free download on their official forums.
Document 5: David Usher: David Usher (born April 24, 1966) is an English-born Canadian musician, best-selling author, keynote speaker and activist, known as the lead singer of the alternative rock band Moist.

Document 8: Brian Robertson (trombonist): Brian Robertson (born October 19, 1979) is the trombone player for the Orange County-based third-wave ska band Suburban Legends and, along with Vincent Walker, is one of the two members to have played with the band since its origin as Bomb Squad. He met other ex-Suburban Legends / Bomb Squad members, trumpet player Aaron Bertram and best friend and trombone player Ryan Dallas Cook through the Huntington Beach High School Marching Band. In 2007, Robertson started to be known by the nickname 'Robot', most likely a reference to the dance moves he does onstage with the band, the first three letters of his last name, and/or to avoid confusion with the band's other Brian, Brian Klemm.
Document 9: Rump Shaker (album): Rump Shaker is the second album of the third-wave ska band Suburban Legends. It was released June 28, 2003 in Los Angeles, California by Lobster Girl Records. The album initially sold 15,000 copies and was subsequently released on Brand New Hero Records in the UK. Rump Shaker was the last Suburban Legends album to feature trombonist Dallas Cook, who died in a hit-and-run motorcycle accident on October 19, 2005. It was also the last CD to feature Chris Maurer on bass guitar and Tim Maurer on vocals. Aaron Bertram and Vince Walker also left the band after this album, but Walker returned as the band's lead singer and Bertram started performing live with the band again from 2009 onwards.
