I am from the class of '74. The song that defines boys of that era for me is, "jump in my car" by the ted mullary gang,
it is definately an aussie song, but still makes me laugh!
my favourite 70's songs are many....but I was in love with cat stevens.
pink floyd....a great band...dark side of the moon....classic
bee gees ....another great band with so many great songs
dolly parton....my all time favourite female singer
olivia newton john.....numerous very good songs too
eagles, elton john, america, crosby steels and nash, slade, deep purple....and the list goes on
