Question:
Madness are an English ska band from Camden Town, north London, who formed in 1976. One of the most prominent bands of the late 1970s and early 1980s 2 Tone ska revival, they continue to perform with six of the seven members of their classic line-up. Madness achieved most of their success in the early to mid-1980s. Both Madness and UB40 spent 214 weeks on the UK singles charts over the course of the decade, holding the record for most weeks spent by a group in the 1980s UK singles charts.
The core of the band formed as The North London Invaders in 1976, and included Mike Barson (Monsieur Barso) on keyboards and vocals, Chris Foreman (Chrissy Boy) on guitar and Lee Thompson (Kix) on saxophone and vocals. They later recruited John Hasler on drums and Cathal Smyth (better known as Chas Smash) on bass guitar. Later in the year, they were joined by lead vocalist Dikron Tulane. This six-piece line-up lasted until part way through 1977, when Graham McPherson (better known as Suggs) took over the lead vocals after seeing the band perform in a friend's garden. Dikron went on to be an actor under the name Dikran Tulaine. Smyth, who left after an argument with Barson, was replaced by Gavin Rodgers, Barson's girlfriend's brother. McPherson was kicked out of the band for too often choosing to watch Chelsea instead of rehearsing. Thompson left the band after Barson criticised his saxophone playing. By 1978, the band had allowed McPherson to return, after filling in temporarily for Hasler (who had taken over vocals when McPherson was removed). Thompson returned after patching things up with Barson. Drummer Daniel Woodgate (Woody) and bass player Mark Bedford (Bedders) also joined the band, replacing Garry Dovey and Rodgers, respectively. After briefly changing their name to Morris and the Minors, the band renamed itself as Madness in 1979, paying homage to one of their favourite songs by ska/reggae artist Prince Buster. The band remained a sextet until late 1979, when Chas Smash rejoined and officially became the seventh member of Madness as a backing vocalist and dancer.

Answer the question at the end by quoting:

Orchestral Manoeuvres in the Dark (OMD) are an English electronic music band formed in Wirral, Merseyside in 1978. Spawned by earlier group The Id, the outfit is composed of co-founders Andy McCluskey (vocals, bass guitar) and Paul Humphreys (keyboards, vocals), along with Martin Cooper (various instruments) and Stuart Kershaw (drums); McCluskey is the only constant member. OMD released their debut single, "Electricity", in 1979, and gained popularity throughout Europe with the 1980 anti-war song "Enola Gay".
The eponymous first album (1980) showcased the band's live set at the time, and was basically recorded by the Humphreys/McCluskey duo, although included some guest drums from Id drummer Malcolm Holmes, and saxophone from Wirral musician Martin Cooper. It had a simple, raw, poppy, melodic synth-pop sound. Dindisc arranged for the song "Messages" to be re-recorded (produced by Gong bassist Mike Howlett) and released as a single (right) - this gave the band their first hit. Dave Hughes, a founder member of Dalek I Love You who joined OMD in early 1980, is featured in the "Messages" video. A tour followed, Winston the tape recorder was augmented with live drums from Malcolm Holmes, and Dalek I Love You's Dave Hughes on synths. Hughes then left OMD in November 1980, replaced by Martin Cooper. The second album Organisation (a reference to the band which preceded Kraftwerk, founded by Kraftwerk's original members Florian Schneider-Esleben and Ralf Hutter) followed later that year, recorded as a three-piece with Humphreys, McCluskey and Holmes. It was again produced by Howlett, and had a rather moodier, dark feel. The album spawned the hit single "Enola Gay", named after the plane that dropped an atomic bomb on Hiroshima. The song was intended to be included on the debut album, but was left out at the final selection. The tour for this album had a 4-piece band line-up, with saxophonist Martin Cooper (another Dalek I Love You alumnus) recruited for keyboard duties. In early 1981, Record Mirror named OMD as the fourth-best band of 1980; NME and Sounds both named the group as one of the 10 best new acts of that year. Howlett then presided over the recording of a further hit single, "Souvenir", co-written by Cooper & Humphreys. It ushered in a lush choral electronic sound. The song also became OMD's biggest UK hit to date. In November 1981, their most commercially successful album was released in the UK and Europe - Architecture & Morality. The group went into the studio with Richard Mainwaring producing. Cooper then temporarily dropped out and was replaced by Mike Douglas, but this change was reversed by the time the album was released and a tour embarked upon. The album's sound saw OMD's original synth-pop sound augmented by the Mellotron, an instrument previously associated with prog rock bands. They used it to add very atmospheric swatches of string, choir and other sounds to their palette. Two more hit singles "Joan of Arc" and "Maid of Orleans" (which became the biggest-selling single of 1982 in Germany) were taken from the album. "Joan of Arc" and "Maid of Orleans" were originally both titled "Joan of Arc"; the name of the latter single was changed at the insistence of the publishers and to avoid confusion. It became "Joan of Arc (Maid of Orleans)" and later simply "Maid of Orleans". In 1983 the band lost commercial momentum somewhat, with the release of their more experimental Dazzle Ships album, which mixed melancholy synth ballads and uptempo synth-pop with musique concrete and short wave radio tape collages. It was recorded by the 4-piece Humphreys/Holmes/Cooper/McCluskey line-up, and produced by Rhett Davies. Its relative commercial failure caused a crisis of confidence for Humphreys and McCluskey and brought about a deliberate move towards the mainstream.

Did they perform with any other bands or artists during this time?
The tour for this album had a 4-piece band line-up, with saxophonist Martin Cooper
