Twelve students (at the invitation of BYU's president) bring their own rock music and demonstrate contremporary "fad dances" for general authorities in the church administration building. Apostle Joseph Fileding Smith says, "I don't know anything about them, and want to see them." Afterwards Apostle Gordon B. Hinckley exclaims, "Nothing like this has even happened in this building before!" Not long afterwards BYU more strictly enforces its ban against contemporary "rock" dancing.
