That Sign Of Leo track is a fantastic sunshine pop tune, really top-of-the-heap kind of stuff as far as that "genre" goes. Well composed, superbly produced and with a very unorthodox/creative psych break that works etc.
I'd personally never think of playing this track in a soul context, but considering that the DJs in the video also spin pure pop like Marion Sodd and Fragile Lime, then I'm not surprised that the Sign Of Leo track is included in their set.
The second cover-up is Teak Wood "See My Girl" on ARC by the way. Also pure pop.
