Robert Browning fluffs his lines

Recorded on 7 April 1889, the year of his death, on an Edison cylinder, reciting “How They Brought the Good News from Ghent to Aix”. Well, the first five lines, until:

“I’m terribly sorry, but I can’t remember me own verses.”

Then he praises Edison’s “wonderful invention”. Possibly it was all scripted – which would make this the first advertisement recorded by a poet.
