It's one of my all time favorite Lynyrd Skynyrd songs...
"Gimme Three Steps" was written by Allen Collins and Ronnie Van Zant, and recorded on March 29th, 1973 at Studio One in Doraville, Georgia.
The song is memorable for its opening riff and story of how Ronnie was dancing with a girl named Linda Lou at a bar called The Jug... when a man, probably the girl's boyfriend or husband, walked in with a gun.
The song is based on a real-life experience Ronnie Van Zant had at a biker bar in Jacksonville known as The Pastime, including having a gun pulled on him, and thus inspiring him to write the lyrics on his way home.
The single wouldn't be released until November of 1973, and wouldn't chart, but it did propel Skynyrd's debut album Pronounced Leh-Nerd Skin-Nerd to huge success.
