"Desperado"

The original by "The Eagles" is good, but this live version by Linda Ronstadt is fantastic:

"Beginnings"

A great song by "Chicago Transit Authority", which later shortened their name to "Chicago" when the real Chicago Transit Authority threatened legal action. The original uncut studio version of "Beginnings" clocked in at 7:54. The last part of that version gets a little tedious, so I'm opting for the 6:31 version:

"Badge"

A song by "Cream", but written by Eric Clapton and George Harrison during a collaborative effort, with a little help from Ringo Starr.

The song title is an inside joke, and the lyrics were never intended to make sense, but the guitar work is amazing:
