On another warm September day, occupying center stage, with only the Boyd Family Singers in the arcade to compete with, I sang to the people as they walked by. For the first 15-20 minutes, nobody noticed me, then a boy of 9 or 10 came from behind me, where he’d been listening from the rim of the fountain, and threw some coins in my case. After my first break I counted it, 4 cents.

I prefer to think that he liked my music, that, having no money, he rolled up his sleeves and fished 4 pennies from the fountain to give to me. The alternative, however, that he had made a childish gesture of disrespect, if not outright contempt, by de minimis tipping, was probably closer to the truth. Over the years, grown men have tossed pennies in my case. One even gave me a dime, then said, “You suck.”

A Spanish man held a toddler by the hand. The little girl bounced to the rhythms of “I Saw Stars.” When I waved a lei at her, she came running, like a bull to the cape. I doubled the lei to make a tiara for her, then sang a verse of “The Hukilau Song.” Her dad gave me a dollar.

Three Danes, 2 women and a man in their early 20s, stopped to dance. After 2 verses of “The Hukilau Song,” I chatted with the women while the man took up my uke and noodled around with some proficiency. All of sudden, he looked up, noticed that the larger group they were with had left without them, alerted the women and hurried off, but not before tossing $3 in my case.

A photographer shot video while I sang “Honolulu Baby.” When he was done, he gave me a quarter.

A 40-something woman with a big hat gave me a dollar; she had no time for a hula.

A small group of Italians wandered separately around the plaza, then reunited near me. One of them, a woman in her mid-30s, kept looking at me. “Have you got time for a hula today?”

Another woman in the group, perhaps 10 years younger, said, “Si.” Two more women joined us. “Do you all want to hula?”

“Si, si.”

Each one put a dollar in my case before grabbing a lei. I positioned 4 dancers, all women, while the 3 men in the group stood nearby and commented loudly as they danced. They were from different places in Southern Italy, from Rome to Calabria.

I had to leave after an hour to meet Mrs. Ukulele at the dermatologist. When I got to his office, I discovered I’d lost my indoor glasses. All I had were my shades.

After my examination, with no medical concerns except the stripes of tan on my feet from my sandals, we retraced my steps. There, on the rim of the fountain, were my glasses, safe in their hard case. Crisis averted, we exited the park, past the profusely podded catalpa, the guitarist at the Imagine Mosaic, the button sellers and cold water men.

Just before stepping out onto Central Park West, Mrs. Ukulele identified the morning glory-like vine with small yellow flowers that grew on the fence behind the benches: thunbergia alata, or Black-eyed Susan vine.
