U.S Radio Stations CD Box Set

[paulineann]

Does anyone know where I can get a CD Box Set of DJ's on U.S. Radio Stations. I believe there may be a Box Set of 5 CD's available commercially, featuring music programmes containing adverts and jingles for the period between 1950's and 1980's. It was mentioned by a caller to the "Big George" late night programme last week on either the 2nd, 3rd, 4th June 2009. I did not catch the title and I cannot access "listen again" on my computer, at present. Any suggestions to the title of the box set greatly appreciated.
