We all know how much work it is to get ready for a concert. We have venues & instruments, costumes & props, movement & placement that are all part of the equation.
Here is an opening number to end all. Please watch Neil Patrick Harris and how every word he sings is clear. He dances, runs, spins & disappears and yet, we hear every word.
All I can think about is just how much he has rehearsed and then some. What a fun performance.
