Join Casey Kasem as he counts down the 40 biggest songs in the nation every Sunday morning at 6 on Oldiez 96.1. All the original shows just as they aired in the 70s. This weekend take a trip back to April of 1972 where you could buy gasoline for 55 cents a gallon, a new home for less than 28,000, and a new pair of Wrangler Jeans for 12 bucks. The number one song of 1972 was The First Time Ever I Saw Your Face by Roberta Flack.
