The Knobs was the name used by "Led Zeppelin" when they first toured in Germany. German royalty did not approve of them using the Led Zeppelin name, hence The Knobs! They will be reuniting for a one night event September 20th, 2019 in Victoria.
For physical events that happen at a specific time. For example a concert, or dance performance. If there are multiple shows, you can still duplicate your event to cover them all.
