A reason I looked for this list of songs is related to what Big Aj Whittle said two posts above--I teach beginners and use I, V chords for guitar--there are TONS of songs to get started with. But when I started to teach ukulele, I prefer to teach the C chord first and the F chord second. Since there are so few I IV songs, I either have the students tap the uke in place of the V chord, or I flip to the key of F and we play all the same I, V songs but using F, C. then I teach the G7 and we're back to another gazillion songs....

Thanks for the thread. It's basically reinforced that I stay in F 'til students are comfortable. And I can't use "Trouble, Trouble on my Mind" with little kids. I"m going to learn it, though.
