Which girls name featured in a top ten hit for david bowie in 1984 and a number one for michael jackson in 1983?

One is symmetrical, one is radial.

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.
