I saw this on the news feed. I guess I never realized that one of his gigs was writing for Elvis, but it makes sense. Some of his hits, like "In the Ghetto" were heard all over once Elvis sang them.
I don't recall his "Memories", although when I listened to it this morning, it sounds vaguely familiar. I used to listen to a lot of Elvis, so it may have been one of those songs I heard and then never really listened to again.
"Don't Cry Daddy" and "A Little Less Conversation" were memorable though, but not much my style. I do recall his brief variety show, but then that was the era of variety shows, so it didn't surprise me and I can't recall watching it a whole lot.
I also didn't realize he wrote "Watching Scotty Grow", which is another emotion-filled song. Bobby Goldsboro sang that one and it was a big hit for awhile.
