Eddy Arnold bought a bunch of brushy land south of Nashville back when he first started making money in his singing career. His fellow country music singers made fun of him for buying worthless "swampland." That worthless land became some of the most valuable land in the area and made Eddy Arnold very rich. That land now is part of Brentwood, one of the wealthiest suburbs of Nashville.
Rest in peace, Eddy Arnold. You and your wonderful voice will always be remembered.
Brentwood, which Eddy Arnold was very involved in developing, may be one of the wealthiest suburbs in all the U.S., not just Nashville.
