The town is at a bit of an accent crossroads really, the 'native' Shropshire accent especially among older people and those from rural areas is I would say the northernmost example of the accents found down in Herefordshire, Gloucestershire, Bristol area. If you go 15 miles east to Telford you will find many more Black Country type accents, go 20 miles north and you start to hear more influences from northern England while 15 miles east and you will get more Welsh accents, all are quite different from each other.
Speaking of St Mary's church, it's deconsecrated now, mostly used for civic events, fairs, exhibitions etc, it's where the photography exhibition seen in the previous photos was located. It does have some beautiful stained glass, much of it came from Frankfurt in the 17th century, I took some pics inside though it's difficult to capture the glass, especially on my phone camera!
