I can't help much here, but I can tell you that "Spanish Two-Stpe" and "Spanish Fandango" or separate songs. The two-step was an instrumental and one of Wills' first compositions. "Spanish Fandango" came much later, and begins something like "My sweet senorita, my own sweet chiquita... the Spanish Fandango/Hold me once more as we glide cross the floor, it's you I adore, my Spanish Fandango." It is on one of those "Best of Wills" recordings from his time at MGM, and I believe it is even available on CD. Look for the collection that has "So Long I'll See You Later," "Still Water Runs the Deepest," "Boot Heel Drag" and other fine numbers.
