When I first heard this track I thought the title was unusual for an instrumental. "I Think It's Going To Work Out Fine" is off Ry Cooder's 1979 album 'Bop Till You Drop', an album made up almost entirely of covers of earlier rhythm 'n' blues and rock 'n' roll classics.
This song was originally a single sung by Ike & Tina Turner and released in 1961.
Sing along if you know the words….  and ease into the weekend.
