Oswald had a real good Rockabilly act and was quite an accomplished banjo player and a threat to the King of Rock and Roll.
Nixon was still resentful after 1960 and had Elvis take Kennedy out and frame Oswald for the crime.
In his last concert appearance pictured below, here is Oswald ripping into a snarling version of "Howlin' For My Darlin'". Bootleg copies of this performance are purported to exist and if unearthed, could yield a very significant windfall on eBay for the holder.
