joining me is patrick riley.ing. >> good morning. >> so, break it down for me, was it live or not live? >> well, i'm not sure. there's no comment from camp beyonce, where there's not a statement you can always count on an instagram from beyonce, she did post her recording the song before the inaugural performance. there have been statements from the u.s. marine band that a performance track was prepared by the band. that's pretty much protocol in terms of big events like inaugurations and super bowls. you mentioned that's protocol. have there been other cases where celebrities have chosen not to perform live but to the prerecorded version? >> either perform live or perform in lieu or perform as a mix. the much-praised whitney houston performance, the super bowl performance of the national anthem in '91, two months after that, whitney did a concert returning from the gulf war and did an acappella performance of it. the performance was recorded before, half lip-synced, happen performed but brilliant no less. >> kel
