Describe Fosco during his singing of the Barber of Seville.

From the text:

Count Fosco, slowly walking backwards and forwards on the grass, sunning himself in the full blaze of the hot June afternoon. He had a broad straw hat on, with a violet-coloured ribbon round it. A blue blouse, with profuse white fancy-work over the bosom, covered his prodigious body, and was girt about the place where his waist might once have been with a broad scarlet leather belt. Nankeen trousers, displaying more white fancy-work over the ankles, and purple morocco slippers, adorned his lower extremities. He was singing Figaro's famous song in the Barber of Seville, with that crisply fluent vocalisation which is never heard from any other than an Italian throat, accompanying himself on the concertina, which he played with ecstatic throwings-up of his arms, and graceful twistings and turnings of his head, like a fat St. Cecilia masquerading in male attire.
