Robbie Williams
Now that covers 3 different decades
I really need to spend some time online and see what I'm missing with Robbie Williams. I know that is a very popular pick in the UK but he really only had a year or two of exposure in the 1999 time frame in the US and then he went away as fast as he came. Angels peaked on the US charts at #53 and Millennium at #72 so there wasn't a big push back then by his US label.
