Several, and they all seem to center around weddings.....the least weird:

Tiny town of about 400, has SummerFest. Boy and girl,(not brother and sister) both "challenged", both orphans; about 20. Basically, the entire Town raised them when the parents were killed. They wanted to get married, so the Town decided it would be the Big Event on Main Street during the SummerFest......at least we got to play the Mendelsshon instead of the Wagner........

Jewish girl marries Presbyterian boy in Methodist Church.....I did a Vivaldi solo for the Mother's Seating (not so weird) but at the Reception mother of the Bride wanted me to serenade the happy couple with ........Klezmer. I played Funder Chuppah.

By far the weirderst:
Lovely Kathleen O'Shea marries Gunter Waldman (or some such name--he had minimal English) Kathleen's father is a Father----Roman Catholic style. Father became a priest after his wife died. Kathleen was married on her parents 50th wedding anniversary so Fr. decided to have a 50th Wedding Celebration in conjunction with Kathleen's wedding......except his wife had been dead over 20 years.....There were 3 cakes--White Brides cake, chocolate Grooms cake and a highly decorated 50th Anniversary cake..........too weird.
