I have a hypersensitivity to racism, but even so I can find nothing racist in Chinese Laundry Blues.

In fact, the only one of Formby's Mr Wu songs that makes me wince is the Air Raid Warden one with its use of the slang term 'chink'. But even that one is not used in malice - rather it is a simple comic pun (poor quality and judgement, admittedly). If I recall correctly, Formby didn't write the 'Mr Wu's an Air Raid Warden' one.

Formby was fantastic. A top-notch entertainer.

As far as racism is concerned, if anything the evidence is that he and his wife had little time for that kind of nonsense. It is widely reported that on a trip to South Africa, Mrs F directed some very blunt words at the Nationalist Party leader who objected to her hugging a little black girl who had given her some chocolates.
