Another useless bit of perhaps useless information: Dolly Parton asked him to record I will always love you and he agreed but said that he wanted 50% of the royalties for it. She refused, he didnt record it then, and since she wrote it she has received over $20m in royalties.
Cant help falling in Love.
Just as a point of interest I went to Gracelands last July and one of the bits of info they give on the tour is that Elvis phoned his recording studio one morning at 4 am having been drinking saying he wanted to make a record which he did and recorded Are You...
