Maybe a hint in these lyrics: Blue Sky, by the Allman Brothers

Walk along the river, sweet lullaby, it just keeps on flowing, It don't worry 'bout where it's going, no, no. Don't fly, mister blue bird, I'm just walking down the road, Early morning sunshine tell me all I need to know You're my blue sky, you're my sunny day. Lord, you know it makes me high when you turn your love my way, Turn your love my way, yeah. Good old sunday morning, bells are ringing everywhere. Goin to carolina, it won't be long and I'll be there You're my blue sky, you're my sunny day. Lord, you know it makes me high when you turn your love my way, Turn your love my way, yeah, yeah, yeah
