Delirious? (known formerly as The Cutting Edge Band) are a Grammy nominated and multi-Dove Award winning English Christian rock and worship band, featuring Martin Smith on vocals and guitar, Stuart Garrard (also known as Stu G) on guitar and backing vocals, Jon Thatcher on bass guitar, Tim Jupp on keys and piano, and Paul Evans on drums and percussion.

They are perhaps best-known for their modern worship songs 'Rain Down', 'Majesty', 'Lord You Have My Heart', 'Thank You For Saving Me' and their 2001 song "I Could Sing of Your Love Forever", which has been called a "modern worship classic"^[1] and is their most popular song in the United States.

The band was made up of multiple personalities from 1993 to 1996, before the decision was made to take the band full time with a finalized lineup. Between 1997 and 2001, the band targeted the majority of its work towards a mainstream audience, with several singles reaching the top 20 in the UK music charts. However, since 2003 the focus has mainly been placed on the CCM market. Former drummer Stew Smith left the band at the end of April 2008^[2], and it was announced via a press release on the 6th of July 2008 that Delirious? would retire as a band at the end of 2009.
