An overlooked cover tune VIII

Think of the ultimate optimistic song for kids, "Zip-A-Dee-Doo-Dah."  Now, imagine it with a considerably slower tempo, a smooth jazz arrangement, and laid-back vocals sung with no hint of urgency.  Steve Miller--yes, the Steve Miller of "Fly Like An Eagle," "Jet Airliner," and "Take The Money And Run" fame--pulls this off.  His attitude while singing isn't the tune's usual heavily caffeinated vibe of "Wow, this day is great!  I'm so happy!"  Instead, it's closer to, "Look around. Signs point to a positive day.  Cool.  Let's sit back and take it in."
