Does anyone know where i can get the introduction to the history of rock and roll video set?

its a 5 disk set and it has an introduction with a lot of people flashing by then it ends by saying, "The History of rock and roll" in huge letters anyone know what i'm talking about and if so where can i find it?|||i dont know if it is the same but time life has a set of dvds titled the history of rock. i got the first 3 for about $40. i looooove them. they cover lots of bands. they have footage from shows long forgotten. i loaned them out to all my friends and several of them ended up ordering them for themselves after they watched them.
