 Jimmy Webb was particularly pleased with the finished product . According to Yankovic , several times during different concerts in New York and Los Angeles that Yankovic was in attendance , Webb would start to perform the original , feign forgetting the words , and then invite Yankovic on stage to help him sing " Jurassic Park " instead . For a Christmas present one year , Webb even sent Yankovic a rubber dinosaur mask as a joke . Yankovic later noted that Webb " was the coolest " .
