Back To Basics
This term which means to retract to the way it used to be and with decency/values *originated in 1993 when the UK prime minister John Major said during one of his speeches, 'It is time to get back to basics: to self discipline and respect for the law...

*A website visitor who is in his/her 40's claims to have used this term well before 1993

*This from another website visitor:
Try doing it till 1992 and it gives 600+ occurances and so on...USage does seem to jump between 1992 and 1994, but the usage of any othe3r term lik "Back Seat Driver" jumps in the same proportion, which probably reflects only the proliferation of the Net, and discards any theory of John MAjor giving the word an Impetus! Cheers, and hope it helps.
