Filming
Just before the fifth series started filming, a pest control team had to be called into the Maryhill studio set when it was discovered that rats had infested Navid's shop and were eating their way through the stock. The alarm was raised after Jane McCarry (Isa) found a dead rat on the set. The high rat population in the area was due to the proximity of the Forth and Clyde Canal
The theme music used on the TV broadcasts of the show is an excerpt from "Cuban Boy", performed by The Cuban Boys, which is itself sampled from Frank Chacksfield's track of the same name from the album West of Sunset. Although it should be noted that on the DVD release of the Complete Series 1-6 (including all the specials), the opening and ending theme tune has been changed to an entirely different theme. The reason behind this is still unexplained, however licensing could be a possibility.
