I was in 4th grade in 1961, the beginning of the US Civil War Centennial. We sang a few folk songs, including Goober Peas, Sweet Betsy from Pike (bowdlerized to make Ike her husband), The Kerry Dancer, The Keeper and The Erie Canal (aka Low Bridge - not the Weavers' song). Also a few show tunes for recital - Getting to Know You from King and I and Oklahoma! title song.
