Bette Midler - "Wind Beneath My Wings"

According to my fuzzy math, approximately 35,482 high school choirs have performed "Wind Beneath My Wings" since 1989. Bette Midler recorded the song for the soundtrack to the movie Beaches, yet Lee Greenwood, Gladys Knight & The Pips, and Lou Rawls also have performed their own versions of the tune long before Bette became synonymous with it.

Additionally, my fuzzy math also counts "Wind Beneath My Wings" as getting 18,932,436 plays during Casey Kasem's "Long Distance Request & Dedication" segment...give or take a few.

Michael Bublé - "Home"

You likely associate Michael Bublé with his covers of Frank Sinatra, Lou Rawls, and other legendary crooners, but this Canadian is no one-trick pony.  Look no further than "Home", a song Bublé co-wrote.  The tune shot to #1 on the Adult Contemporary Chart back in 2005 and helped launch his international success.    

Larry Graham - "One in a Million You"

Larry Graham probably could have pranked lots of people pretending to be Lou Rawls.
