Famous quotes containing the words upper and/or stage:
“When my old wife lived, upon
This day she was both pantler, butler, cook,
Both dame and servant, welcomed all, served all,
Would sing her song and dance her turn, now here
At upper end o’the table, now i’the middle,
On his shoulder, and his, her face afire
With labor, and the thing she took to quench it
She would to each one sip.”
—William Shakespeare (1564–1616)
“She came out on the stage in yards of pearls, emerging like
a favorite scenic view, flashed her golden smile and sang.”
—Robert Earl Hayden (1913–1980)
