• Miles Davis played the trumpet on this track. Davis had covered "Human Nature," which was written by Toto keyboard player Steve Porcaro, and the group convinced him to record with them. Toto guitarist Steve Lukather told the story to George Cole, author of The Last Miles: The Music of Miles Davis, 1980-1991:
  "Miles wanted to cut the horn at Jeff's [Porcaro - Toto's drummer] studio [called The Villa] and we were all over there cutting the Fahrenheit record. So just in case, we cut the track and left the melody off - we just left open spaces. When Miles got there, we said 'Hey man would you mind just playing the tune? Just blow on it and see what happens? If you don't feel comfortable that's cool.' We had the music, so we ran it down together with him and he was kind of playing around the melody - he wasn't really playing the melody. So we figured, we're not going to tell Miles Davis what to play, so we said, 'Miles, we have a take of this, would you mind just giving it a listen and play whatever you want?' He says 'Okay, I'll play like that. You like that old s--t right?' So he gets out the Harmon mute and he played it down - one take. We're all stood there completely freaked out - it was unbelievable. At the end, the song just kind of fades out, but he just kept playing the blues. I was sitting there with chicken skin on my arms - it was unbelievable moment. And that's how we ended the record - with just Miles blowing. Later on, [saxophonist] David Sanborn came down to play on a different tune on the record and he'd heard that we had cut a tune with Miles. He said: 'I gotta hear it,' and so we played it and he flipped and said 'Please just let me be on the track!' So he doubled the melody and played a couple of flurries. So we got Sanborn, Miles and us on one track - that was pretty cool."
