I often include a medley of Creedance Clearwater songs in my Arranger KB perf set. My favorites include: Have You Ever Seen the Rain, Lodi, and Looking Out My Back Door.
Others include: Bad Moon Rising, Cotton Fields, Down On The Corner, Good Golly Miss Molly, Hey Tonight, The Midnight Special, Who'll Stop the Rain, Proud Mary, and Green River.

Note: Direct Order Online has today just released a brand new song-style for Green River.
They also have these song specific CCR Styles available.
