"Ned and John, the Mona Motor Oil Twins, from Council Bluffs, Iowa, and station KOIL will broadcast a special program over WTMJ, the Milwaukee Journal station from 7 to 7:30 and from 10 to 10:30 tonight. They will sing a number of popular songs of today and play a few Hawaiian guitar selections. Listen to the twins tonight over WTMJ."the morning of Tuesday, May 10th.My impression here is that the group was very short-lived. The Encyclopedia of American Radio lists entries for a Mona Motor Oil Trio, and a Mona Motor Oil String Quartet.
What ultimately happened to ned and Jonh we may never know. The great depression was hard on the Mona Motor Oil Co. before the crash, the Mona Motor Oil complex was expanding down South 6th Stree. but after things were bad. Barnsdall Corp. acquired the company in 1932. They sold KOIL to promoter Don Burden in 1953. The stories about Don Burden deserve their own post and he too will have his day.
