 Yankovic entered the studio to record " Jurassic Park " on July 16 , 1993 . Backing Yankovic were Jon " Bermuda " Schwartz on drums , Steve Jay on bass , and Jim West on guitar . " MacArthur Park " contained an actual orchestra complete with a strings section . " Jurassic Park " , however , features synth strings courtesy of keyboardist Brad Buxer , who programmed the section himself . Intermixed during the interlude are various dinosaur sound effects courtesy of Sandy Berman ; Berman had previously created dinosaur yells for a major theme park attraction , and loaned Yankovic the sound effects . At 3 : 53 in length , the song is considerably shorter than the original , which clocks in at 7 : 21 . Largely , this is due to the fact that the middle section featured in the original — the so called " After the Loves of My Life " section — is omitted from Yankovic 's parody .
