The clip is from a Richard L. Smith EVP investigation aboard the WWII submarine USS Cavalla, in drydock at Galveston Island, Texas. Rich was given a lockdown free run of the ship during one night and a chapter on that investigation is in his book, "Everyplace I Go Is Haunted" . His website www.paratexas.com is a huge resource for EVP information and offers a great deal of original studies, stories, photo spreads , and related paranormal info. Rich also offers personal tutoring and instruction on EVP technique from his home studio in Alvin, Texas (near Galveston).
