A touch of a rainbow...

Of course my favorite Rainbow Connection
Then there is Somewhere over the rainbow
Sunshine, Lollipops and Rainbows
The Rolling Stones She's a Rainbow
Elvis Pocket full of Rainbows 
Sia Rainbow
Miley Cyrus Rainbowland
Kesha Rainbow
And finally one for the meaning - Kacey Musgraves Rainbow - Something to always remember...
