Grammys organisers explain why drakes acceptance speech was cut off

I think there may be some confusion here!

The 63rd Annual Grammy Awards did not actually take place, so there was no acceptance speech by Drake that was cut off. The 63rd Annual Grammy Awards are scheduled to take place on March 14, 2021, but they have not yet occurred.

However, if you're referring to a previous year's Grammy Awards, I'd be happy to help you find information on why a particular acceptance speech was cut off. Could you please provide more context or clarify which year's Grammys you're referring to?
