Paul played together with Michael McDonald a mix/rendition of Cecilia including parts of McDonalds hit "Will It Go Round In Circles" on the 2nd Maui show August 14.

Paul seems to be very relaxed on that probably un-rehearsed song, doing just a jam and improvising a little bit more than usual.
He played 2 songs with Keola Beamer and 1 song with Michael McDonald. The rest of the setlist looks similar to the concert in San Francisco - except for American Tune.
