That won't happen. As much as I don't see how Danny's show is actually "Dance Anthems" when it's loads of fresh and mostly unreleased new dance music. Unlike Dave Pearce's version which was well established dance tracks that everyone knew.
Radio 1 has always had a dance show in that time for years. Remember, Judge Jules used to be there from the late 90's into the early 2000's, and then moved to 7-9 on a Saturday night. It is at the perfect time as people are getting ready to go out.
I do think Danny's show needs to be renamed though as it's a bit misleading with loads of upfront tunes. Maybe bring in a new presenter and put Dance Anthems on a Sunday evening, playing erm dance anthems. Where it always should of been.
