 " Friends Forever / What 's Going to Happen " was composed by Fordham , Marx and Lopez . " Friends Forever " is a parody of 1950s @-@ style musical numbers in general , and " We Go Together " from Grease in particular . However , this was not the original plan . According to Fordham , " I was really shocked when I got the demo back , because I had never envisioned a ' 50s number . I did mention ' We Go Together , ' just as an example of I wanted a cheesy , fun , happy ending kind of a thing . "
