How deep is the ocean?

Irving Berlin was one of the most important American songwriters (born in Russia but emigrated to USA when he was very young).
This is one of the simple beautiful songs that he wrote in 1932. A song with many questions except for the statement in the first line which says "I'll tell you no lies".
He wrote hundreds of songs, many becoming major hits, which made him famous before he turned thirty. During his 60-year career he wrote an estimated 1,500 songs, including the scores for 20 original Broadway shows and 15 original Hollywood films,[8] with his songs nominated eight times for Academy Awards. Many songs became popular themes and anthems, including "Alexander's Ragtime Band", "Easter Parade", "Puttin' on the Ritz", "Cheek to Cheek", "White Christmas", "Happy Holiday", "Anything You Can Do (I Can Do Better)", and "There's No Business Like Show Business". His Broadway musical and 1943 film This is the Army,[9] with Ronald Reagan, had Kate Smith singing Berlin's "God Bless America" which was first performed in 1938.
