Janet Jackson keeps her brother's memories alive virtual duet

Janet Jackson is opening up for the first time about a duet with her brother Michael Jackson that she is reviving 2 years after his death.

Jackson took to the stage in London on Thursday and performed their 1995 song Scream as video of Michael Jackson played and his voice filled Royal Albert Hall.

The reworked duet follows in the footsteps of jazz pianist and singer Nat King Cole and his daughter, Natalie Cole. In 1991 she turned her father's famous 1961 recording "Unforgettable" into a father-daughter duet.

Janet Jackson said she did the original duet at the request of her brother one year ago.

Janet Jackson said, "I was on the Rhythm Nation tour and Mike actually asked me to do a song with him and I told him no. I didn't want to do it. I felt I had not come into my own and I had not fully made a name for myself. And I did not want to ride anyone's coattails. And I remember being in the Janet Tour a few good years later and he asked me again if I would do a song with him. And I felt, at that point, I'd carved my own little niche in this world of music and I felt okay, I can do this now and that's how it came about."

Jackson said that performing the song alongside her brother again is not difficult.

She said, "It feels great -- just listening to and hearing his voice," adding that on stage she finds herself, "remembering the experience of recording it."

Jackson decline to comment to the press on the 2 year mark of her brother's death, instead taking to social media this week with a simple message on Twitter on the June 25 anniversary: "I miss you, I love you."

Jackson wraps up the European leg of her tour this week then heads to North America, Australia and Africa.
