Esther Chillini celebrated her 70th birthday tonight at the Pink Martini concert at Wolf Trap. Pink Martini led the audience in “Happy Birthday” and they had a cake for her. During their encore pianist Thomas Lauderdale lit the candles on Esther’s cake and invited her up to the stage. Esther and an unnamed friend made their way to the stage and joined in on percussion during the last song. Esther blew out the candles and sat at the piano with Lauderdale. Esther’s friend was waving what appeared to be homemade fans with people’s faces on them. She pranced around the stage, interacting with every member of the band and clearly more comfortable with the spotlight than Esther. But I am sure Esther had a happy birthday.
