A man has gone on trial accused of manslaughter over the deaths of Fisherman's Friends singer Trevor Grills and tour promoter Paul McMullen at Guildford's G Live venue.
Grills, 54, and McMullen, 44, were killed after a steel door collapsed on them in February 2013. The band had been due to perform at the venue.
David Naylor, 57, of Bridgnorth, director of Hi-Fold Doors Ltd, faces two counts of manslaughter by gross negligence. His company also faces a charge of breaching general duty regarding articles and substances for use at work.
Describing the incident as an "avoidable tragedy", prosecutor Zoe Johnson QC told Guildford Crown Court that previous door failures had occurred at other sites, reports Get Surrey. "[Naylor] had so many opportunities to learn but he did not take them," she said.
Naylor denies all charges. The trial continues.
