The single starts out with Fortune Faded, the song they wrote in 2001 for their next album (which ended up being By The Way) and was meant to be a big hit, but they didn't like how that version came up. This new version, in my opinion, does not have the same power the older one had. In case you haven't heard it, John has different (less) backing vocals on it, the chorus melody is different, and there's no acoustic guitar. This version, however, is still cool.
The second track is a Californication remix by Ekkehard Ehelers. My first reaction when I found out this was gonna be on the single was denial. Why go back to the horrible remix days!? Well they did. The track is good for one listen, for curiosity, but that's it. Definately not worth it.
The last track is Tuesday Night In Berlin, an end of show jam recorded (yeah you've guessed it) in Berlin, in March 2003. The track is one of their most experimental jams. It starts out with the usual lineup (Flea on bass, John Frusciante on guitar, Anthony Kiedis on vocals, and Chad Smith on drums) plus Ekkehard Ehelers, who does sound effects on the song. In the middle of the song, the jam ends for a second, and then Flea starts playig his trumpet. Soon John joins him on bass, and then Ekkehard Ehelers. So the lineup ends with Flea on trumpet, John on bass, and Ekkehard Ehelers on the effects.
The song is worth a listen especially to hear John play bass and Flea playing trumpet (in case you hadn't before) but it's the kind of song you can get fed up with after a while, unlike another end of show jam, Nothing To Lose, from the Can't Stop single. For more jams you can also check out the Californication single.
