I have come across a fantastic website called chordie. It is loaded up with chords and lyrics for what looks like thousands of songs. If you play a fretted instrument, you need to check this out.
Not only does this site provide a large quantity of songs, but it shows chord diagrams for nine(!) flavors of guitar, banjo, mandolin, and ukulele. In addition, the chords are in a format that allows for automatic transposition, which is incredibly helpful for a fat-fingered beginner like me with a lower-than-average vocal range.
Now instead of "Six Little Ducks" all the time, we can all sing Weird Al's Yoda.
Stay tuned for details on my new CD, The Deluded Ukulele: A Collection of Non-standard 80's Standards.
