After completing
high school, Zell played for the
Freddy Martin and
Russ Morgan bands before he got his
draft notice. He served in the army from 1965 to 1968. During his time in the army, he played for the
North American Aerospace Defense Command (NORAD) band known as The Commanders along with
Dave Edwards and
Richard Maloof, future Welk musicians. In early 1968, while with the NORAD band, Zell had a second chance to audition for Welk. Zell was asked to do a
television commercial for U.S. Army
recruiting and part of the job was to do an
interview for the Welk show and to play trumpet for the band. After his performance on that show, Welk hired him into the band upon his completion of his military service which was nine months away. From 1968 until the television series ended in 1982, Zell was one of
The Lawrence Welk Show's most popular musicians and was often featured in trumpet solos, including "At the Cross", "
Hot Lips" and "
A String of Pearls". Zell was the protégé of Welk trumpet great
Norman Bailey, who gave Zell one of his trumpets, made of gold. As a
born-again Christian, he was also involved in
gospel ministry, pursuing both
Christian and
secular music, doing many
concert dates and making albums. Later in life, Johnny became pastor of The Church of New Beginnings in Pacific City, Oregon, a position he held for over 17 years. ==Personal life==
