The heartbeat that starts this song isn't an actual human heart. David Dickey, who played bass on the track, created the sounds by hitting muted strings on his guitar. In our interview with Gerry Beckley
, he explained: "Every fourth one, we heard this little kind of pumped heartbeat, and said, 'David, how are you doing that?' And he said, 'I'm not doing anything!'
It took a while to solo all the tracks to realize that little extra 'ca-clump' was my foot coming off the sustain pedal on the piano. You have to listen closely, but those are the funny little things that happen, so we kept it in. It made an interesting little bit for all the headphone fanatics."
