12 o'clock Chimes at Kidderminster, Worcs

Please have a look at my newsletter (New every 1st of the Month): https://soundbow12.wixsite.com/mysite-1 Can anyone guess the tune its playing? I'm not sure if they ring every hour or if its only 9am, 12noon, 3pm and 6pm? Definitely worth the visit. On the first day they had the shutters closed so it was quite quiet, however on the second day they were open and I stood around the back!
