Started to listen - at least 3 factual inaccuracies within the first 5 minutes... already wishing to scream at the set!!! Unless I'm mistaken Grainger started using the phonograph in 1907 - not 1906 as stated... the presenter got the name of the Society wrong, and other points wrong as well..... I'm obviously too much of an anorak! I shall persevere though.....
