Yes, it is really quite amazing. The man had unshakeable confidence too. Despite being invited to many a recital by wags who would invite all their friends just to get a good laugh at McGonagall, and supply them with rotten vegetables with which to pelt the poet, McGonagall never lost faith in his muse and seems to have believed that it was God himself who commanded him to WRITE, WRITE, WRITE, and recite! He also acted in Shakespearian plays like Hamlet and MacBeth, playing the aforementioned characters and others. That must have been quite something. If I had a time machine I would go back just to see it for myself.
