God save us all!!!

My bro is recently into 70’s music!!! Help….this ALL started with “Happy Feet”. He JUST had to listen to “Boogie Wonderland” again and again because the penguins did such a good rendition (yes, I find it cute too but that’s not the point). Then he went on to get ALL the other 70’s disco songs…ABBA….”That’s the way I like it” and other songs from Earth, Wind & Fire. Something happened last night increased this mania. He watched the 70’s contest/programme on MTV last night and had MORE songs to get. Gosh. Help!
Ring my beeee-eeellll……ring my bell.
