I'd have included Big Joe Turner's ,"Shake, Rattle, and Roll" and "Honey Hush". A thirteen year old Etta James with the Peaches, doing "Roll With Me, Henry" and Bo Diddley doing "Hey, Bo Diddley". All of those come in before "Rock Around The Clock" and around the same time as "Rocket 88". You simply don't get a drawing of Bettie Page straddling a rocket on the sleeve of the other records like you do with "Rocket 88", a big plus.
"Shake, Rattle, and Roll" may have beat them all to the punch, it's hard to tell how long Big Joe was doing that number before he recorded it. Big Joe was a force of nature
