To me it looks / sounds like it's played stright from sheet. Many times we see the players are so focused into the paper / sheet that everything gets a bit "mechanical" and liveless.
Also it may feel a bit boring or uninspired when they don't find time to do some instrumental variations and put some personal feelings into it.
Usually that's going to loose up and get better the more secure the player feels after some repeats of the song.

Keep on Rockin'
