If you listen to it really close,when Chester & Mike sing the part : "May your love never end,and if you [here] need a friend,there's a seat here alongside [here] me." You can hear a some sort of "click" sound. (2.54 and 3.01 on the official album track,and 2.14-2.20 on the official acapella one). Has anyone else noticed that ? Or I am just going nuts ?
