I have a similiar problem with material for kids. Here is my list for all ages: Found a Peanut, We're on Our Way to Grandpa's Farm, Yankee Doodle, On top of Ol' Smoky (On top of Spaghetti),How O;d Are You my Pretty Little Miss, Little Moses, Row your Boat, Skip to my Lou, You are my Sunshine, Lisa jane, Old Grey Mare, Goober Peas, Clementine, Goodnight Irene, When Johnny Comes Marchimg Home Again, Grandfather's Clock, Y'all Come, Home on the Range, She'll be comin' round the Mountain, Follow the Drinking Gourd. All of the above are on a guitar, with sing alongs. I mix in an autoharp and play: Pachelbel's Canon in D (it's so pretty), Greensleeves, Molly Malone, Elizabeth's waltz, Wayfaring Stranger.I'll use a fiddle or harmonica for Amazing Grace, Were You There When they Crucified My Lord, and Sweet Hour of Prayer.
