There’s much fun to be had at the Lyric Hammersmith, where that ever-enterprising company Cartoon de Salvo has taken over the function room at the Hop Poles pub, directly across from the theatre. Here, in their new guise as magnificently named pub rockers One Trick Pony, the Salvos treat us to a gig with a difference.

Deconstructing the disintegrating dynamics of a long-established “function band” can only work if the four actors convince absolutely as skilled amateur rock and rollers. Thankfully they do, with lively Brian Logan pounding his keyboards in full Adam Ant regalia and Neil Haigh spot-on as the Thom Yorke-wannabe frustrated by his weekly diet of Brown-Eyed Girl and We Are Family.

Director Alex Murdoch, doubling as a lovelorn if nifty bass guitarist, could sharpen the focus in places and play up the idea that the Ponies view these pub bookings as the aural equivalent of Botox, preserving a sliver of freed youth while all else is kids and mortgages. Let’s hope they rock on.

Pub Rock until 20 February (0871 2211722, www.lyric.co.uk).
