Maroon 5
American pop punk band
Could Maroon 5 have hypothetically held a concert at Roman Colosseum?
The Roman Colosseum had a capacity of 87,000 people.  Maroon 5 has held concerts at Brazil's Allianz Parque, which has a capacity of close to 44,000. Almost 30,000 people attended Maroon 5's 2015 Madison Square Garden concert over two days.
How many spectators could the Roman Colosseum hold? How many people were in attendance at Maroon 5's largest concert? Is #1 greater than #2?
