^Christina had nothing to do with the release of OM, it´s success in europe was/is entirely based upon public popularity and requests to radiostations....as a consequence, BMG decided to release the song as a physical single in a number of countries, and, as a teaser for the live-DVD, a video taken from the concert was used as the official video to "Oh mother".
The era, as in Christina promoting the album, stopped when she became pregnant, she just finished up the tour
I LOVE IT
