For
Be Bop A Lula here's a suggestion:
You really need to have (if you want a good guitar backing)
_CBOOGMS Country Boogie Med(140) with real bass, drums and 2 guitars.

Insert the rights chords and the Shots were it goes (in the key of E)
"(E.d)She’s the woman in the red blue jeans" for 2 bars then "(E.d) blah,blah," again for 2 bars etc
I don’t think Peter likes us putting actual chords of tunes up on the forum for legal reasons, but its pretty easy (E, A7, B7) is all you need.
I just did this in a few minutes added some reverb to the guitars and panned each left and right and it all sounds v good.

Hope this gets you started.
