"I'll Do as Much for You Someday" is a song written by Ed G. Nelson and Ed Nelson Jr.
Slim Whitman recorded it for RCA Victor on February 3, 1949. It was released as a single, as the flip side to "I'm Casting My Lasso Towards the Sky", in April of the same year.
Billboard gave a "satisfactory" review, writing: "Okay ballad number here, with performance less than adequate."
In 1962, Eddy Arnold released his rendition on a single (RCA Victor 7984, "I'll Do As Much For You Someday" / "Tears Broke Out on Me"), but it was the other side that became successful.
