Answer by taking a quote from the following article:

The Wildhearts are an English rock group, formed in 1989 in Newcastle upon Tyne. The band's sound is a mixture of hard rock and melodic pop music, often described in the music press as combining influences as diverse as The Beatles and 1980s-era Metallica. However, this characterization is denied by the band, who see their influences as being far broader, as shown in the song "29 X The Pain", which lists many of group leader Ginger's influences. Despite several top 20 singles and one top 10 album in Britain, the Wildhearts have not achieved major commercial success, owing in part to difficulties with record companies and many internal problems often relating to recreational drugs and depression.

The Wildhearts formed in late 1989, after Ginger was sacked from the Quireboys. An often-told story from this time period is that Ginger decided to start his own band after falling down a flight of stairs with a bottle of Jack Daniel's but emerging with the bottle intact. Had the bottle smashed, he would have slit his wrists with the shards, but instead he resolved to form a band in which he could exercise his songwriting skills, rather than just playing guitar as in his previous bands. Throughout the band's career, Ginger has written almost all the songs himself.  Initially called the Wild Hearts (two words), the band originally included singers Snake (ex-Tobruk) and Dunken F. Mullett (ex-Mournblade), who both joined for short periods. Nine demos were recorded in 1989 and 1990 with Snake singing on four and Dunken on five. These demos remain unreleased and displayed a sound resembling Guns N' Roses, with the Wildhearts sound still to be developed. Some of the demos were produced by Ric Browde and intended for an EP release that never materialized, though these demos are occasionally found on unofficial releases. In March 1991, Ginger reluctantly took over on lead vocals despite his reservations, as he has never thought himself a good singer.  After many early personnel changes, the line-up solidified around Ginger on guitar and vocals, CJ (Christopher Jagdhar) on guitar and vocals, Danny McCormack on bass and vocals, and Dogs D'Amour drummer Bam. This line-up released two EPs in 1992, Mondo Akimbo a-Go-Go and Don't Be Happy...Just Worry.

What did they do after releasing the two EPs?
