1. The riff is doubled (1958 Les Paul Standard through a 100 watt Marshall Plexi) but it's in mono. It's also pretty loose, as you can hear either one or both parts misplayed at a number of places in the songs. Of course, that wouldn't get by today, but did that ever bother any of us before?
2. The bridge begins at 1:24, but the guitar ad libs don't begin until 1:50. At that point the amp noise increases, perhaps as a result from switching in the delay.
3. Something that you don't hear too clearly in the final mix is the new guitar riff that begins at the outro at 4:40.
4. If you listen all the way to the end you'll hear two endings. The first is rather tame, but listen a little more and you'll hear a more wild ending from the previous take at 5:50.
