Honestly Cutiepie, the best way to find out what Elvis songs were on what albums, movie soundtracks, etc. is to simply ask your questions here!! With all of the Elvis fans that are members of our TCB-World Family, I'm sure someone out there would be able to answer any questions you have regarding where to find songs!!
Personally, while I think FUNNY HOW TIME SLIPS AWAY is a great song, I really enjoy the way Elvis did it in concert!! So whenever I want to listen to this song, I always pull out one of the concerts where Elvis performed this song!!
