This is Bernie Taupin's second solo album and it is excellent.From the rockers Born on the fourth of July to his smooth ballads Venezuela and Love(the barren desert). This is a great album for anyone who has followed Elton and Bernie's career.

Positive

I went to two stores trying to find the exact brand name products that Sandra Lee insist we use. Frustrated, I asked the store mananger who told me that the products I was looking for, Campbell's fat-free mushroom soup and Jello refrigerated vanilla pudding cups are no longer available in my area.Why make such a big fuss about using this or that brand when they aren't even available? I won't waste any more time travelling around town looking for the exact brand names needed to make the recipes in this book.I have better things to do! Maybe this book needs a "use-by " date before even more products become obsolete.

Ex Output:
Negative

After 3 c sections, I need all the help I can get. I started with the size Large (when I was a size 12). I have moved on to the medium (I am between 8-10 now). The medium is REALLY tight, but does the job. I prefer the large day to day because I have 3 children under 6 to run after, and it is a bit more comfortable for that. These things are really great. I can't believe I didn't know about them after my first 2 c sections. They should send all women home with them after giving birth!

Ex Output:

Positive
