Kempyyyyyyy Carl perkins had this song in the charts a full year before Elvis. His version was different as well. Carl and his brother were on their way to NY to do this live on TV, they had a car accident which killed Carl's brother. Elvis waited until this song had done all it could in the charts before he re released it.

I have an interview that Carl Perkins did in 98 just before his death and he states this actuall event.
