 The composer Granville Bantock was enlisted as musical director in 1897 at the ballroom to provide music each weekday for six hours of ballroom dancing . To begin with , as the tower was being erected , he was in charge of a " semi @-@ military band " that played outdoors with the fear that the tower might fall upon him and his players . Bantock is quoted as saying , " The noise of the riveting of the tower while we were playing ... reminded me of the anvil music in Das Rheingold " . Bantock often played for the workmen during their lunch breaks , when they could frequently be heard saying , " play it again , guv 'nor " .
