The Great Atlantic & Pacific Tea Company and with a name like that you knwo they thought highly of themselves and with good cause.
A&P began in 1859 as a small chain of coffee and tea shops in new york. By the turn of the century they were the first national grocery chain in America with over 200 stores. It grew 8 fold over the next 15 years to 1,600 stores. By 1930 it was the world's largest retailer. It's decline began in the 1950s and over the next half century bankruptcies and buyouts left it what it is today.
Today the word Gypsy is the next worst-thing to a racial slur. Ostensibly Harry had studied gypsy folk music while traveling with gypsy bands in Istanbul. it's hard to corroborate knowing he was imprisoned after 1914 and in the US by around 1921 at the age of 25. When that Turkish tour happened... I cannot say.
the A&P Gypsies performed together in 1923 through 1936 and subsequently cut a number of sides for Decca and Brunswick.
Horlick died in July of 1970.
