After the defection of keyboardist Andrew Haskell shortly before their debut LP was released on TVT/Island, Matthew Dublin and Darren Beckett also left Ambulance LTD to form a band called The Red Romance with the addition of Adam Chilensk on bass, leaving Congleton as the only remaining member.
In 2008, Ambulance LTD hired a backing band consisting of Ian Fenger on guitar, Xander McMahon on keyboards, and Jeremy Kay on bass.
TVT also attempted to sell artists' back catalog, resulting in Congleton, along with labelmates The Polyphonic Spree, to file a lawsuit against the label and its parent company Universal Music Group in June 2008.
Michael Di Liberto writes and records under the name “prehd” and released a new album called “Cache” in April of 2023 on all streaming services.
