My father was a top baritone / tenor in his day, many many years ago. So as a child I was surrounded by great singers, including people like Judy Garland etc. I used to sing with my dad sometimes and developed a "good ear" as they used to call it. True, Frank Sinatra was / is amazing! But, on the whole, I prefer Michael Buble. He is a far more relaxed singer with an outstanding voice and a character that allows him to put great emotion into any song. For me personally, I find him far more enjoyable to listen to ... oh, and of course to look at too, lol! Frank's version of "You make me feel so young" was like all of his work ... immaculate timing, vocal tone, interpretation etc. But personally, I still prefer Michael's more relaxed version. It is just that tiny bit more believable! :o)
