It was, in truth, not necessary to "kill for a ticket" or even "fight for a ticket", as the flyers for Life Is Rhythm said it would be. I arrived at the Lyric Theatre in London's Shaftesbury Avenue at two minutes to eight, paid £15 for what I thought was an upper-circle ticket, was shepherded into the dress circle in a bid to form a theatre-going quorum, and sat through the brief, mildly engaging performance of Catalan dance and African drumming.
