Forty students from the Jerusalem Academy of Music and Dance took a classical approach to the popular flash mob as they “flash waltzed” Tchaikovsky’s Waltz of the Flowers at the new Sarah Wetsman Davidson Hospital Tower of the Hadassah Medical Center at Ein Kerem in Jerusalem last week. Surprised doctors, patients and passersby joined in the fun.

The impromptu concert was part of Good Deeds Day, an annual event that originated in Israel in 2007, and now takes place in over 50 countries worldwide. On this day, volunteers reach out to the less fortunate and the vulnerable.

The Academy students enjoyed the day so much that they decided to schedule regular concerts at the hospital.
