I'm looking for very short instrumental riffs (most likely guitar riffs but other instruments; bass, sax, keys etc. are perfectly OK ) that when heard, you immediately know the tune they are from. 
Examples
Stones "Satisfaction"
Beatles "Day Tripper"
Chuck Berry "Johnny B Goode"
Usually these riffs are in the intros to the songs but they don't have to be. Mainly looking for riffs that are very short and very well known.
Any more titles appreciated!
Thanks
