I do a few oldies from time to time. As an intro to Tommy Roe's "Sheila" which I couple with Buddy Holly and the Crickets' "Peggy Sue", I usually finger the chords (I use A, D, A, E - repeated) while lightly beating on all the strings just a little above the bridge. This results in a somewhat satisfactory immitation of the sounds of the original recordings.I also saw this technique used by someone who did "Kaw-Liga".
You need to be careful doing this, though. It is not difficult to break a string this way.
