TheSingingMixer: #BillyJoel's #TheLongestTime is pure #doowop #acapella & a lovely declaration of love for his new lady, #ChristieBrinkley. @Hunter Evenson crafted a brilliant #streetcornerchoir #cover & left it open to #collab. This has been on my list forever, so I jumped right in! If you're feeling #oldschool #takethelead & #joinmycollab! It really feels good! #tsm #longesttime #HEven
