This is a current Southwest Airlines ad. There's a near-hemispherical blue-colored stripe (ribbon-like) streaking across the sky.. It appears to be following the curvature of the earth. The song starts with la la la la la or love love love love love it's a beautiful day. Anyway, it's a good little fun sounding tune that I would like to have. Thanks. Those are not la las; they're more like luh luhs.
