In the early 1920s, Spiller's son Edward took over the running of the business and, with the aid of the popular accordionist and bandleader Joe Gregory, sold musical instruments alongside the pre-recorded music.
In the late 1940s the shop moved around the corner to a larger premises on The Hayes.
In 2006, the shop's future was made uncertain when the site rent was increased by Spillers' landlords, Helical Bar, who stated that they were keen for the shop to survive.
A local campaign to save the shop was initiated, including a petition initiated by Owen John Thomas (then the Assembly Member for South Wales Central) and supported by members of the Welsh Assembly, Manic Street Preachers and Columbia Records.
