I post them together for three reasons.
First, because I enjoy bragging about the fact that Albert Shea, the tenor (second from left) in the Buffalo Bills was my cousin and bears an uncanny resemblance to my Dad that still freaks me out. I like to watch The Music Man now and then because it’s like seeing my Dad alive again. Also, it’s a fun musical.
Second, I post The Music Man clip to introduce the second two clips, which prove indeed that “singing is just sustained talking”.
Third, I forget. But it was probably pretty important, so you should watch all three because they are awesome, especially the third one, which I saved for last cuz it’s best.
