The recital
A soldier stationed in the South Pacific wrote to his wife in the States to please send him a harmonica to occupy his free time and keep his mind off of the local women. The wife complied and sent the best one she could find, along with several dozen lesson & music books.
Rotated back home, he rushed to their home and thru the front door. "Oh darling" he gushed, "Come here... let me look at you... let me hold you ! Let's have a fine dinner out, then make love all night. I've missed your lovin' so much !" The wife, keeping her distance, said, "All in good time lover. First, let's hear you play that harmonica."
