How would you paraphrase this part of this poem?? Please HELP!?!?

Question

"So now it is vain for the singer to burst into clamour

With the great black piano appassianato. The glamour

Of childish days is upon me, my manhood is cast

Down in the flood of rememberance, I weep like a child for the past."

Answer 1

The fat lady has sung. I'm old, and sad and remember my past.
