She always knew that her birth father was a professional musician.
"My best friend in high school was sure it was David Bowie," said Truly Carmichael, who was adopted at birth in Texas. Carmichael, a classically trained singer and folk-harpist, wasn't disappointed to discover that her father was Michael Johnson, the Minnesota-bred pop singer ("Bluer Than Blue," "This Night Won't Last Forever") turned country chart-topper ("Give Me Wings," "The Moon Is Still Over Her Shoulder").
Three years ago, at age 40, Carmichael started searching for her birth parents, received information from the adoption agency and reached out to Johnson via e-mail. After several lengthy exchanges via e-mail and phone, they met and began making music together in Seattle (her living room) and Nashville (his living room). Now, she sings with him on a track on his new album, "Moonlit Déjà Vu."
"I was nervous," said Carmichael, who spurned his first two pitches to sing because she was too busy. "It was very businesslike because we don't have years of familial comfort. I didn't know if he was including me because it's nice to have your daughter on board or because he likes the way my voice sounds."
"I kept saying 'less vibrato now,'" Johnson, 68, who produced the session, said in a separate interview.
"She's trained as an opera singer. Finally, I said 'no vibrato,' knowing that there would be some vibrato."
"I'm really happy we did it," said Carmichael, who long ago segued from music to theatrical costume design and eventually software documentation. "It's more fun to just sit in the living room and just play music together. That's pretty remarkable."
Carmichael will join Johnson for that one song, "One Mile Apart," in concert Saturday at his CD-release concert at Hopkins Center for the Arts. It will be her first concert performance in "I can't remember."
