Graham William Walker, known by his stage name Graham Norton, (born 4 April 1963) is an Irish actor, comedian, television presenter and columnist. He is the host of comedy chat programme The Graham Norton Show on BBC One in the UK and BBC America in the US. Hot Press has described him as "the 21st century's answer to Terry Wogan", with both men sharing an Irish background and the common link of being a BBC Radio 2 presenter and the BBC television commentator of the Eurovision Song Contest. Norton has won the BAFTA TV Award for Best Entertainment Performance on five occassions.

Norton was born in Clondalkin, a suburb of Dublin, but grew up in Bandon, County Cork, Ireland to a Protestant family. He was educated at Bandon Grammar School, in County Cork and then University College Cork but did not complete his studies.

In 1992 his stand-up comedy drag act in the Edinburgh Festival Fringe as a tea-towel clad Mother Teresa of Calcutta made the press when Scottish Television's religious affairs department mistakenly thought he represented the real Mother Teresa.

Bill Laswell (born February 12, 1955 in Salem, Illinois and raised in Albion, Michigan) is an American bassist, producer and record label owner.

Laswell ranks among the most prolific of modern musicians, being involved in hundreds of recordings with many collaborators from all over the world. Laswell's music draws upon many different genres, most notably funk, various world music, jazz, dub and ambient styles. He has also played or produced music from the noisier, more aggressive end of the rock spectrum, such as hardcore punk and metal.

According to music critic Chris Brazier, "Laswell’s pet concept is 'collision music' which involves bringing together musicians from wildly divergent but complementary spheres and seeing what comes out." The credo of one record label run by Laswell, and which typifies much of his work, is “Nothing Is True, Everything Is Permitted”. Though projects arranged by Laswell may be credited under the same name and often feature the same roster of musicians, the styles and themes explored on different albums can vary dramatically: Material began as a noisy dance music project, but subsequent releases have been centered around hip hop, jazz, or backing spoken word readings by beat generation icon William S. Burroughs. Similarly, most versions of Praxis have featured guitarist Buckethead, but have explored different permutations with each new album.
