The personal highlight of my collection:
The first two singles by Randy Crawford from 1972 and 1973 for the Columbia label. For reasons unknown to me, these regular releases, "Knock On Wood" and "Don't Get Caught (In Love's Triangle)", have been produced in much smaller quantities than the corresponding promo singles. While these contain the respective title song in stereo and mono, the songs "If You Say The Word" and "Magic Wand Of Love" can only be found on the B-Side on the regular singles. After these two releases, Randy Crawford left Columbia. It took me more than 20 years to find them.
