Before watching that video all the IBM employees would have had to get together and sing songs. It was a long standing tradition at IBM that all employees at the start of the day had to get together and sing songs praising IBM and Thomas Watson. You can still find copies of the IBM song book floating around the Internet.
When my Dad started in the late 60s IBM had discontinued the morning song tradition.
