Her first LP, with the tongue-in-cheek title "Mrs. Miller's Greatest Hits", was issued by Capitol in 1966. Made up entirely of well-known pop songs, it sold more than 250,000 copies in its first three weeks. Gary Owens wrote the album's liner notes. "Will Success Spoil Mrs. Miller?!" followed, and "The Country Soul of Mrs. Miller" came a year later. Miller sang for US servicemen in Vietnam, performed at the Hollywood Bowl, and guest starred on numerous television talk and variety shows. She also appeared in Roddy McDowall's film "The Cool Ones", where she sang "It's Magic". Eventually, public interest in Miller began to wane, and Capitol Records dropped her from their roster in 1968. She released one album, "Mrs. Miller Does Her Thing", on the small Amaret Records label, before issuing several singles on her own Vibrato Records label. She recorded two albums of material at Radio Recorders studios in Hollywood that were issued by Dunhill Records, which went unnoticed. Her last known recording was a self-released EP in 1970. Miller officially retired in 1973, when interest in her career had almost completely vanished. She spent her remaining years doing work for various charities. She lived in a condo in Northridge, California, until the earthquake in 1994; she then moved into a retirement home. She may have been the inspiration for a similar act called Mr Miller and the Blue Notes, who released a 1966 version of the Herman's Hermits hit "Mrs. Brown, You've Got a Lovely Daughter". Elva Miller died in Garden Terrace Retirement Center, in Vista, California, in 1997, aged 89. She was interred in Pomona Mausoleum, at Pomona Valley Memorial Park, in Pomona, California. Two years later, a compilation CD of her work was released on Capitol's Ultra-Lounge label: "Wild, Cool & Swingin,' The Artist Collection Vol. 3: Mrs. Miller." "-" indicates did not chart
