"Hound Dog" started with composers Jerry Leiber and Mike Stoller who produced it themselves with Big Mama Thornton in 1952. The Japanese version is included for variety because the tune was sung in just about every genre and language since it's inception.
The Elvis Presley version was based on the Freddie Bell and the Bellboys interpretation he saw in Las Vegas. Elvis sang it on the Milton Berle Show then on Steve Allen's. The next day it was recorded at RCA along with "Don't Be Cruel" Both side went to number one in 1956.
