With the letter, the artists "want to show the vital importance of the UK live music industry". They write that the live music industry wants to be self-sufficient, as it was before the restrictions with the pandemic, but that it is impossible in the current circumstances. They believe that financial support from the state is crucial to preventing the British live music industry from collapsing.

Following the release of the letter, artists, venues and festivals have begun posting photos and clips from their latest live shows on social media under the hashtag #letthemusicplay. Paul McCartney, the Rolling Stones, Iron Maiden and Cher are some of those who have posted under the hashtag to show their support for the UK live music industry.
