AMERICAN pop-punk-crunk-rap celebration Party in Your Pants Tour rolled into the O2 Academy for the penultimate leg of its 11-date UK stint on Wednesday night, presenting an evening of revelry that was all about the fans.

Elvis Costello-sounding, Rubinoos-influenced The Leftovers kicked off proceedings with a blast of seventies-style powerpop, before a self-published MC Lars installed his unique brand of post-punk laptop rap; BFS front man Jaret Reddick joining 27-year old Lars on the Industry-lamenting ‘Download This Song’.

A subsequently rampant Zebrahead set saw the California-based quintet open with singles Rescue Me and Postcards From Hell. Popular tracks Playmate of The Year and Anthem later followed, while vocalist-guitarist Matty Lewis was praised for performing through a bout of illness.

Headliners Bowling For Soup then ploughed through a barrage of sing-a-long anthems, both old and new.

Fan favourites Almost, Punk Rock 101 and High School Never Ends were featured as the Texan four-piece dealt with material from their nine-album strong back catalogue, covering over a decade of releases.

Touching also on latest album Sorry For Partyin’ with new single My Weena, the quartet were accompanied by a series of visual displays throughout.

A growing pop punk institution of notable musical synchronicity; BFS gave an interlude-rich performance, laden with stops, restarts and voiced crowd ensembles, suggesting clearly high spirits the venue-over.

Famed hit Girl All the Bad Guys Want and Katy Perry’s Hot ‘N’ Cold rounded off a thoroughly entertaining set, with the crowd-suggested, SR-71-penned 1985 serving as the model encore.
