As part of the group's 40th-anniversary celebrations, a UK and European tour was announced in March 2019. A retrospective deluxe boxset entitled "Souvenir" was also announced in August 2019. The 40th anniversary collection includes the group's forty singles, including new release "Don't Go". It also contains 22 previously unreleased recordings from the group's archive, selected and mixed by Paul Humphreys. Two audio live shows, one from 2011 and one from 2013, are also included together with two DVDs bringing together two more live concerts – Drury Lane in 1981 and Sheffield City Hall in 1985 – plus "Crush – The Movie", and various BBC TV performances from "Top of the Pops", "The Old Grey Whistle Test" and "Later... with Jools Holland". The boxset was nominated for "Best Historical Album" at the 2021 Grammy Awards.
