To B or not to B?

I can reach a B-C-D!

C and D for good days, like today(!) B on normal days, as of recently :) With a quick warm-up to that range I can hold it for eight bars and glide almost the complete chromatic scale, breath allowing.

So should I sing the B after all, for Summertime?

So many many many factors to consider...

I have a million and one things to say, but now's not the time... It's so aggravating not so have self-time nowadays, where the whole world spins in a freaking whirlwind of events that leave you breathless yet unable to pause, still.

More at a better time.
