I’m no fan of “The Star-Spangled Banner” — IMHO the national anthem should be “America the Beautiful” as sung by Ray Charles — but this rendition is special. Madisen Hallberg, a graduate student at Portland State University, was recording the song for an online graduation ceremony, when passing professional singer Emmanuel Henreid heard her and joined in. The circumstance produced a surprisingly moving rendition of a tune we usually take for granted.
