THEME:   Both words of a two-word phrase begin with PA   
GOOD ONES:     Title:  
PA DE DEUX [not 
pas de deux]   
Messages from Mozart?   NOTES   
Private organization?   ARMY   
Fat head?  LIPO [as a prefix it heads the term]   
William and Kate's set   TELLY [TV set to Brits --- I thought a social set so far above my own I didn't know what it was]   
Fowl language?   PEEP   
Talking points?   ROSTRA [literally the points from which they speak]   
Guitar support   KNEE [simple enough]   
Acts inappropriately?   EMOTES      
BTW:   ___ favor   POR [In formal text, foreign words are italicized.  In Xwords, they're not; hence, the word "favor" looks like English but here is Spanish.  I don't know if 
por favor is used so much in English that it is appropriate for us, but I like the idea of using a word that is the same in two languages.      
PARCHMENT PAPER and PAISLEY PATTERN seem rather redundant.      
RATING:
