McCormack became the bass player in The Wildhearts[1] in 1991, and soon relocated to London with the band, enjoying success during their commercial peak, before the splits in 1997 and 1998.
McCormack went on to form and front The Yo-Yos, with Tom Spencer (ex-Sugarsnatch/The Lurkers), and the band released an album on Sub Pop Records,[2] but they eventually split in 2000.
Following a prolonged absence from the music scene for a number of years, McCormack took the stage to play bass at his 40th birthday.
Ahead of the mini-album's release, McCormack almost died after suffering an aneurysm in late 2015 – which later culminated in him losing his lower leg.

In early 2022, The Wildhearts announced they were taking an indefinite hiatus, which meant the subsequent cancellation of all their tour and festival dates.
