It is very hard to listen to a collection of songs like this without comparing them with the original. And though Bette Midler has a decent voice, she just doesn't compare with Rosemary Clooney, some of whose greatest hits she sings in this collection. She certainly can't compare with Rosemary on the "dialect" hits like "Come On-a My House" and "Mambo Italiano," which are definitely far below Rosie's versions. She does somewhat better on most of the other tracks, of which I think the best is "Sisters," with Linda Ronstadt doing the Betty Clooney part. Most of these I'd consider OK if I didn't constantly have to keep comparing them with Rosie's originals.
The clearest example of the effect of comparing her performance with the original is that I think the absolute best track on the CD is "Memories of You." And that is obviously because it's the only one of all the songs in the collection that I can't compare with Rosie's version. I assume that she must have recorded it -- otherwise it wouldn't be in this collection. But if I've ever heard a Rosemary Clooney version of "Memories of You" I have no recollection of it. So all I have to compare it with is the Four Coins' version. And though the Four Coins' version of the song is a great one, and I love it, I don't try to compare female soloists with male groups. So in this case, Bette's version stands on its own. And, as I think I'm making clear, it's a nice version. But I don't know how Rosie did it.
One other comment. Her version of "This Old House" doesn't seem to be inspired by Rosemary Clooney's as much as the other songs in the collection. It is probably closer to the country-music original than Rosie's is. (Never having HEARD the country-music original, I don't know for sure). But I really STILL prefer Rosie's.
I think my advice would be: Listen to this, I suppose, once to see whether you like it. But then go and get the ORIGINALS and see how much better they are!
