who you think should sing national anthem for may/pac?

i love the whole event of boxing, including music, i like some of the low key shows, which play music inbetween fights. best anthem ive heard since i got into boxing is keisha cole, she didnt add to much twist to it like others. second best ive heard is R kelly with the kind of rnb beat in the background, i think it wa really cool. also, which song do you think Floyd should come out to as we know pac is coming out to his awful singing. Floyd should come out to this, or atleast have it as a highlight reel before the real walkout. Would also be a good idea to have it for his last fight, just incase he loss doe. this is also a song id like to see him come out to. i know it wont happen, i just hope its not a high lil wayne again. anyway, i think it should be Beyonce or Mariah Carey singing national anthem, the two top diva's who can sing as good as Ali can fight. They are ATG's. and just cause i like her face, and she can sing, ariana grande has a ton load of followers on twitter and insta. he walks out with bieber cause of that. shes in her prime, very good singer, looks good, all good. i believe floyds team would have the last say. Madonna? Cher? atg's during these anthems ill be nervous as hell, im sure some of use will be more. what you reakon?
