Bernie,
Although The Accordion Centre's website gives the address of the business as 131 Midland Street as seen in Post #17, if one goes to the Thomson Local.com site and types "accordions" and "Birmingham" in the appropriate search boxes, it comes up with The Accordion Centre and lists the address as 5-7 Garland Street. If one then goes to Google Earth (or Google Maps) and whams in 5-7 Garland Street, the Street View view shows a company called Matts and Jenkins Ltd. By looking up Matts and Jenkins on the Internet (Google, Internet Explorer, Firefox, etc.), you're taken to the company's website and lo and behold! abracadabra! the address is 5-7 Garland Street!
Mystery over. The house on the corner of Garland Street (or Green Street) and Garrison Street is a residential home and not The Accordion Centre.
Case proven.
Best wishes, David
