In early 2001 Ginger announced that he was reforming the Earth vs the Wildhearts lineup of the band for a tour later that year. This lineup (consisting of Ginger and CJ on guitars and vocals, Danny McCormack on bass and vocals, and Stidi on drums) soon ran into difficulty due to McCormack's battle against heroin addiction, and on several dates of the comeback tour Toshi (from support band AntiProduct) stood in as bassist. By 2002 McCormack was once again clean and the band started recording a new mini-album and also toured the UK. The tracks intended for the album were released in the UK in late 2002 across three formats of the "Vanilla Radio" single, and as the mini-album Riff After Riff After Motherfucking Riff in Japan. "Vanilla Radio" reached the top 30 in the UK singles chart, and in early 2003 work began on a full-length album. However, during recording, McCormack checked himself into a rehabilitation center to deal with an alcohol problem, leaving Ginger to play the bass parts on the songs that were newly recorded for the album. McCormack's place in the live band was filled by "Random" Jon Poole, who had already worked with Ginger on his Silver Ginger 5 side project.  The album The Wildhearts Must Be Destroyed, released in 2003, had a very commercial sound, full of short simple pop songs with little of the heavier rock style which often featured on previous albums. The band also managed to get a US record deal with Gearhead Records, which released Riff After Riff in 2004, a compilation of songs from the UK post-reformation singles (all of the songs from this release are also found on the Gut Records compilation Coupled With). Riff After Riff was the Wildhearts' first US release since Earth vs the Wildhearts in 1994. The release was also promoted by a tour, mostly as the support band for their ex-support band, The Darkness.  Then in early 2005, Ginger dissolved the Wildhearts again, citing a mixture of his own personal problems and a lack of commitment within the band. He briefly joined the Brides of Destruction before setting out on his own as a full-time solo artist. In typically unpredictable Wildhearts style, Ginger then reformed the Wildhearts once again for a one-off gig at Scarborough Castle (Rock In The Castle) in September 2005. The 1994-1995 line-up of Ginger, C.J., McCormack, and Ritch Battersby played at this gig.  Once again, the Wildhearts reformed in December 2006 and played a single live show at the Wulfrun Hall in Wolverhampton. This line-up saw Ginger joined again by C.J., Ritch Battersby and a new bassist, Scott Sorry (ex-Amen). This line-up soon became official, with plans made for a new album in 2007.
