Being working on a "complete" Elvis collection and notice that the RCA Albums collection is missing Elvis in Concert along with the singles. I working on rectifying that, but at a bit of a loss of how to do this right. Are the complete concerts on CD in good quality officially? If you had to deal with just the CD release how would you sequence it? I am thinking the singles should be separate because of the overdubs. Also is Unchained Melody, If You Love Me (Let Me Know) and Little Darlin' different from the Elvis In Concert/Singles (different performances)?
