Shares in Mean Fiddler rose 12% to 53p yesterday ahead of confirmation that it had received an approach that could lead to a takeover bid. The company, which owns the Jazz Café and Astoria music venues and a partial stake in the Glastonbury Festival, pulled out of a planned £11.8m share sale and £5.7m acquisition of Media Internet Telecom last year. Vince Power, the company’s founder and chairman, is believed to be on the verge of selling his share in the company after the failed deal.
