McCormack became the bass player in The Wildhearts 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 frontThe Yo-Yos, with Tom Spencer, and the band released an album on Sub Pop Records, but they eventually split in 2000. He re-joined The Wildhearts when they reformed in 2001, but was dropped midway through a tour. He rejoined again in 2002, but left once more in 2003. At the time the group's frontman Ginger penned an open letter to Kerrang! magazine documenting his close friend's drug problems and wished him a complete recovery. Unexpectedly, he returned to The Wildhearts in 2005 for a live DVD. McCormack briefly played with Dogs D'Amour before re-forming The Yo-Yos in 2005, and recording an EP, "Given Up Giving Up". He subsequently supported his younger brother Chris McCormack's band, 3 Colours Red, on their final tour of Germany, but the band fired Danny McCormack halfway through a UK tour in 2005 following further drug problems. He continues to write and live in South Shields. In late 2006, McCormack announced on his MySpace page that he is working on a new project that is tentatively titled 'The I-Told-You-So's'. Following a prolonged absence from the music scene for a number of years, McCormack took the stage to play bass at his 40th birthday. The special event featured two gigs in one night at Camden Barfly in London on 17 February 2012. Performances came from a reunited Yo-Yos - consisting of McCormack, Spencer and Rich Jones along with guest drummers - as well as a covers set featuring Chris McCormack, Andy Cairns, Ritch Battersby and Stidi. The support band for the night was Plan A - which featured former Wildhearts guitarist Jef. In 2015, McCormack founded a band called The Main Grains which would later release an EP called Don't Believe Everything You Think. 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. The four-piece punk n roll group later played support on a few UK dates of the Ginger Wildheart Band's July 2016 tour. During one of the shows, McCormack and Ginger played onstage for the first time in more than a decade - with Ginger later announcing he and McCormack had finally buried the hatchet and were friends again. He re-joined the Wildhearts in 2018. In 2019, McCormack recorded bass with The Wildhearts for their new album "Renaissance Men", the first album the band had released since 2009's Chutzpah and McCormack's first since 1997's Endless Nameless. The album charted at 11 in the UK charts following its release in May 2019. McCormack continues to tour and perform with the band.
