not sure i'd classify the George Young or Jon Thomas as 'shakers, they sound a bit too straight mod/soul jazz to me...? both nice tracks tho
i think my list would include things like Ernie Fields Orchestra 'Workin' Out', The Page Boys 'Barracuda', The Gee Cees 'Buzz Saw Twist', Jimmy Gordon 'Buzzzzzz', The Four Instants 'Discoteque', JC Davis 'The Splib', probably some twist tracks as well...
*plug* Londoners can come and hear some tonight at Jukebox Jam! alongside the R&B, early soul, blues rockers, etc *plug*
