A polished group performance from the X Factor-originating band was let down by some poor solos.

The quartet were great together as they rattled through their repertoire of pop covers including Coldplay's Yellow, Britney Spears' Oops I Did It Again and Christina Aguilera's Beautiful.

Their rendition of the Liverpool FC anthem You'll Never Walk Alone was genuinely hairs-on-the-back-of-your-neck time.

When it became time for one of the group to sing solo, though, each sounded flat, off-key and rather embarrassing.

Jon struggled to sing as he went walkabout among the crowd and Mike's serenading of a girl - apparently pulled from the audience - was excruciating.

Nessun Dorma, the overplayed opera classic, was extremely well performed and crowd-pleasingl. Sinatra tune My Way went down a storm.

The announcement that their record label, EMI, is to give G4 a third album and another chance to spread this particular brand of popera and hyped-up choir boy rock was met with universal approval by the Brighton Centre audience.

Hopefully, there won't be too many solos on it.
