Pretty much my MO too, Joe. I feel no shame that I need to prompt my memory on songs I don't sing very often! :-)

The 'transpose' function is useful in that, where you have the chords included on lyric-pages, you can hit the 'transpose' slider and hey-presto, all the chords are changed to the new key!

The 'Set-List' function in Onsong is very useful indeed, and has the bonus that, as you move through the list, the lyrics are there behind it in case of critical memory-failure.

I have a Konig & Meyer mount which enables me to either mount the iPad holder direct on a straight mic-stand, or use the bracket to side-mount it on a boom-type mic-stand.
