The sound quality in the available (tape recorder) video is poor. Heavily compressed. But there are some good (remastered) recordings available on YouTube. For example :

That other old story (in similar vein, haggling for a bargain) "Three Ha'pence A Foot", 1932, can be found on YouTube direct from 78 r.p.m.
