Got the message about 20 after I'd arrived at Christmas Island. Shirley was not one of the Andrews Sisters, it was Maxine, Laverne and Patty. I remember them well as I'm quite old!!!
13 is "Carol of the Birds" which I found on Google.
10 I have Christmas Party as it refers to three political parties. It could be Christmas Parties.
23 Queen's Christmas Message (Age messed up, shown as GAE)
I have to go out now but will be back later with explanations about your other queries.
