This song is actually a compilation of three sections of two takes. 0:00 to 0:55 is take 7, 0:55 to 1:00 is a different section of take 7, and 1:00 to 4:10 (the end) is take 26. Take 26 was faster than take 7 and in a different (higher) key, so in order to make the tempo and keys match, the tape of take 26 was slowed down slightly.
