Yes, I am positive about Out on the Floor being played at the Wheel in the 60's.
Not really surprising it isn't often mentioned in this context. It didn't achieve the kind of status it later attained but was another good, solid sound, like so many others.
I believe Dobie Gray's version of The In Crowd was played, although I personally never heard it there. The Ramsey Lewis version was the one at the time.
BTW, I have never seen a comprehensive playlist of Wheel sounds, It was something I wanted to see generated when I returned to the Soul scene a few years back now. 'As comprehensive a list as it is now possible to produce' was the aim and the Twisted Wheel Forum website seemed at the time to be the obvious repository, rather than start from scratch and reinvent the Wheel, so to speak. So I contributed a list of some 250 Wheel sounds to the site, of which 3 were initially refuted, then subseuently accepted. The Shakers, One Wonderful Moment was one, as I recall. Thelma Houton. Baby Mine possibly another. None, I think, were attributed. C'est la vie Then the website disappeared into the ether, along with the playlist thus far and I've not had contact with either since. Nor. at the risk of being contentious, have I heard a satisfactory, properly representative 60's Wheel set played at any of the 3 venues since it's 'reopening'. I am not alone in this view.
Don't understand your comment re the Soul Sounds label, Pete (S). Apologies if I've mis-read you. They are all non-UK releases?
