Have a go at playing along with the videos on this page.  You can slow down the speed using the little cog icon at the bottom of the YouTube page.

The first one is for practising the Cups song.  Thanks for finding this one Theresa!
The second is a suggestion from D2, 'Brown Eyed Girl',
And finally, The Swimming Song.  Firstly, a clip with chords to play along to, and then the McGarrigles performing.
