Early years 
Cross went to Belmont Secondary Modern School, William Forster Comprehensive. He began his music career playing in different bands, in Tottenham, North London, his major early influences were The Small Faces, Desmond Dekker, The Crazy World of Arthur Brown.
Later he joined Stoned Rose, in Preston, Lancashire, alongside Pete Hughes and Mick Carroll, who later went to form Ritzi, but also decided to study a long standing interest in psychology at college.
Tiger Lily and Ultravox 
In 1973, he returned to go to Art College in London, begun studying Art and Psychology meanwhile he also answered the ad for members to form a 'new' band, put by in Dennis Leigh, an art student in London, thus forming Tiger Lily along with guitarist Stevie Shears, drummer Warren Cann joined shortly and violinist/keyboardist Billy Currie added the next year. During the Tiger Lily phase he began to name himself as Chris St. John.
In the meantime, as Chris Allen, he wrote several songs with his brother Jeff for the latter's glam rock group Hello.
Tiger Lily spent a year constructing/arranging and rehearsing their songs written mostly by Leigh in Modrenos, a mannequin refurb workshop in Kings Cross, London. After playing gigs from 1974 to 1976, in the latter year the band chose to call themselves Ultravox! and signed to Island Records, while St. John also changed his stage name to Chris Cross (while Dennis Leigh called himself as John Foxx).
In 1979, after three commercially unsuccessful but influential albums – Ultravox! (1977), Ha!-Ha!-Ha! (1977) and Systems of Romance (1978) – and a tour through USA and Canada, original vocalist John Foxx and guitarist Robin Simon, who had replaced Stevie Shears a year before, left Ultravox, so Cross worked on another part-time "Purely for Fun" project with Pretenders' guitarist James Honeyman-Scott, one of his favourite guitar players, Eddie and the Hot Rods' vocalist Barrie Masters and The Rods drummer Steve Nicholls.
With Midge Ure added to Ultravox, the band continued working more on their unique synthesiser sounds during the recording of their successful Vienna album. By that time, he and Ure were close friends, together directing music videos such as Bananarama's Shy Boy and 'The Telephone Always Rings' by Fun Boy Three. Cross took part in the Band Aid video and wrote the music to "The Bloodied Sword". After another few successful albums – Rage in Eden (1981), Quartet (1982), Monument (1983) and Lament (1984) – and the last which was less successful, U-Vox, and a tour in 1987, the band drifted into other projects and he says, "never got round to working on Ultravox".
Retirement from music 
Ultravox revival 
In November 2008 it was announced that Ultravox were to embark on the "Return To Eden" tour in April 2009, plus two festivals and additionally a Best Of Ultravox CD/DVD was released by EMI.
The 2012 album release Brilliant, included Chris Allen as co-writer with Billy Currie and Midge Ure on all tracks. The album was promoted with a UK theatre tour and a series of European dates.
During the time in which Ultravox was led by John Foxx, he used a White Gibson EB-3, Fender Fretless Precision bass guitar and electronica on an Ems Synthi AKS Synth and later a Mini Moog Ampeg amp and 8x10 Speaker.
Cross's distinctive grey bass guitar is an Ibanez RoadStar from the early 1980s; this guitar has been used on many of Ultravox's albums and was Cross's primary instrument during the first stage of the 'Return to Eden' Tour in 2009.
