KYDZ Keighley Youth Theatre will mark the milestone next month with a concert, Musical Mashup. The two-hour show – comprising songs and short dramas – will feature 24 children, aged between nine and 16. KYDZ grew out of Keighley youth theatre HYT, which disbanded after 30 years of presenting original theatre devised by its young members. "We followed in HYT's footsteps by presenting full-length musical dramas written by leaders through improvisation with the youngsters," says a KYDZ spokesperson. "In the latest show, there will be solos and group songs including classic pop, modern chart hits and musicals.
