'Living In A Ghost Town' was released as a 7" single in the UK on April 23, 2020, where it peaked at #61.

As Keith Richards puts it out the day of its release on the internet: “We cut this track well over a year ago in L.A. for part of a new album, an on-going thing, and then the shit hit the fan. Mick and I decided this one really needed to go to work now.”
'Living In A Ghost Town', penned by Jagger & Richards, was released on the band's Youtube channel a few days after the band performed 'You Can't Always Get What You Want' during the event One World - Together at Home to celebrate COVID-19 workers on April 18, 2020.
The track was recorded in early 2019 at British Grove Studios, London, and Henson Studios, LA, USA, up to Mick Jagger's home studio in France in April 2020.

About the songs
Nearly 80 songs recorded by the Rolling Stones entered either the UK or US charts since 1963, twelve of them peaking at #1 ['Satisfaction', 'Get Off Of My Cloud', 'Paint It, Black' and 'Honky Tonk Women' were #1 in both countries].

The early years also were the most prolific and, whereas most titles were not yet penned by the Jagger-Richards tandem, record labels Decca [in the UK] and London [in the US] would issue singles at a frantic pace, building the band's reputation as the Beatles' most serious threat.

However, no global marketing strategy would emerge before the 70's, and both countries cultivated their differences in their respective discographies, as would their affiliates in other parts of the world.

The richness and diversity of the Rolling Stones singles discography is mainly due to the fact that, during the 60's, Decca would consider singles an independent market from the LPs' one, whereas London would use this format as a 'lift' for album sales. Therefore, British singles would offer non-album tracks [except for compilations], and Decca England would pass on a few US releases, while the US would opt for different B-sides and be a little more productive.

US exclusive couplings and singles would however often be released on Decca in Europe, notably in Scandinavia for which UK would exclusively press 'export' singles [Denmark, Sweden and Norway also pressed their own records and imported regular UK releases].
