These songs are published also as a Johnny Ramone: The Final Sessions 12' maxi. Read more here.

Johnny Ramone's participation on Swing Cats: Special Tribute to Elvis album was a surprise for many people, because Johnny had been out of the music business and very quiet for years. These songs are also known as the 'Johnny Ramone final sessions.'
Johnny was a big Elvis Presley fan. He had a great collection of Elvis related items.
Johnny by the way was the bestman at Lisa Marie Presley's wedding to Nicolas Cage. They both were good friends to Johnny and Linda in the later part of Johnny's life. Also he was a good friend with Slim Jim.

Next I write here comments by Danny B. Harvey who plays bass on Swing Cats: Special Tribute to Elvis album.
- The day Johnny Ramone came into the studio to record the backing tracks for these two Elvis songs, he showed up in the studio with a prototype of a Japanese "Johnny Ramone signature guitar." He told me he no longer owned any guitars, or amps, because he had sold them all when he retired. The only reason he had this one was because the guitar company had sent it over for his approval prior to production. I asked him why he didn't own any musical equipment and didn't he still play and practise around the house? His reply was: "Do baseball players go to battling practise when they retire? Of course not, so why I do need to practise, has told Danny B. Harvey.
