But it was released as a single in The US John ... as the "B" side of "If I Could Build My Whole World Around You". And it did chart on Billboard's listings (though nowhere near as high as the "A" side) at #68 Hot-100 and #27 R&B.
It looks like some of the US Radio Stations treated the 45 as a "Double 'A'" with WOL in Washington D.C. listing both sides as high as #2 on Jan 29th 1968.
