1) Anthony Kiedas' vocals have come a long way since the Pepper's first began in 1983 and this track is a great example. Although musically it's not very challenging, Anthony's performance is flawless, which is exactly what you'd expect from a big budget major label album.
2) The ad lib at 3:08 is the only part that sounds like it might be left from a scratch track. Notice the paper rustling in the background.
3) I always felt that the mark of a good vocalist is how well he can sing harmonies, even with himself. You'd be surprised at how many pretty good lead singers just cannot hear a harmony to save their lives. In Tell Me Baby, listen to Anthony's layered background harmonies on the choruses at 1:30 and 2: 30 and the outro on 3:26. Once again, they're perfect without sounding like they were cut and pasted. He's singing lots of naked 5ths, which many vocalist have a hard time hearing.
4) The outro has a couple of additional instruments with the appearance of udu drum and maracas.
5) Not much to say about the great Chad Smith's drumming on the second video except that he's as solid as it comes while playing a groove that might challenge other drummers. It's as perfect as a loop, yet breathes like a real drummer, which is exactly what you want from a drum track.
