The Bottom Line:

The very first single and mono, too.

Levon Helm plays drums on this pink label rarity. According to Chas Keep this first single sank without a trace.

Originally there was a picture sleeve that can be seen in the booklet of the Island Remasters edition of Stormbringer!

Mold numbers:
wipx 1057 //1 and wipx 1058/2.
Apparently there was some confusion as on both sides the orginal numbers have been striken out. They prove that either the original order was reversed or some employee made a mistake.
