A lot of times I’ll write-off or dismiss a song that’s too popular or on-the-nose for a band a to play and this one might qualify. However, it’s a great exercise if nothing else to dig into and see how it works. For example, just learning the chords and melody to the intro to Crazy is pretty magical to me.
And if your band has a female singer and plays covers and takes requests you can bet money this one will come up. Might as well at least learn the outline.
