Jeeves & Wooster jeeves and wooster say what ho!

Aha, you see that great big horn thing, Jeeves?
-One could ghastly miss it, sir.
Well, now you have to speak into that.
Or sing into it.
Or play the trombone into it.
If you want to make a record, that is.
-I see, sir.
If not, of course, best to leave the
dash thing alone.
-Quite, sir.
Now, I don't quite know about this, Jeeves,
as it happens.
Apparently there's a fellow in a white coat
at the other end of the horn thing.
Beyond the wall, if you take my meaning.
-I see, sir.
And what this fellow does is
he turns this handle
as you sing into the horn thing.
-Or play the trombone, sir.
Or play the trombone.
And as it turns this handle
this wax record goes round and
sort of... well, makes a record of your
trombone playing.
-I think that that system has now been somewhat
superseded, sir.
Really, Jeeves?
The disk is nowadays more often
revolved by electricity I understand, sir.
This giving more uniform rotational speed.
Yes, I, I... I think that's enough
about electricity, Jeeves.
-Very good, sir.
Electricity is all very fine, Jeeves.
But will it replace the bicycle?
-Possibly not, sir.
