organ instrumental music!Need help identifying a piece of instrumental music(50s,60s,70s)?

Was in a bar the other night and they were playing music mostly from the above decades. Heard a familiar song that was mostly a solo organ. It sounded kind of rock n roll, kind of jazzy. Iorgan instrumental musict was instrumental, had no works. Any names of famous or recognisable rock organ music would help lots! Thanks
Was it
Booker T & the M G 's - Green Onions

No idea! Any other informatioorgan instrumental musicn you can offer? Maybe even narrow it down to a definite decade?

Two great jazz organists from the 60s that I have are Brother Jack MacDuff and Jimmy Smith, electric organ.
