So today I decided to have a bash (if you heard m playing, you'd know that's the right term!) at learning "Its Been A Blue Day". I fired up The Shads version to have a good listen on headphones and was both horrified and yet strangely pleased to hear a mistake from Hank (it seems he is human after all).
At around the 1m 15 second point, just after the last three notes of what I call "the middle, twiddly bit", you can distinctly hear an extra note, which is abruptly cut off. It sounds as if he was intending to play on, and perhaps go straight to the next verse.
I dare say this is old news to most members, but I thought I'd share my discovery nonetheless, as it made me feel a little less critical of my own efforts. Just goes to show, we can all make mistakes at times
