Jim and Liz Beloff have done a sterling job with The Daily Ukulele. It is what it says it is: "365 Songs for Better Living". It includes a section on tuning, holding, strumming, transposing, and chord alternatives plus a chord chart for C6 tuning. The songs are in alphabetical order with a comprehensive index and cover a wide range of song choices from The Beatles, Elvis, Willie Nelson, to twenties and thirties favourites along with seasonal and children's songs. Chord diagrams are at the top of each song. I have used this book every day since I bought it - so it really is My 'daily ukulele'. Recommended, even for those who tune in D6.
