Beertz started playing guitar when he was 13 years old. In less than a year, he was playing in a band called the Belvideres. In the 70s, he played in a band called the Witt Brothers and then with the Coffee Band along with members, Bobby K and Mike Cummings. Starting in 80s, he formed the "Funn Band" with Bobby K and Bob Annette eventually becoming the band "Krackerjax" with Debo on bass. Krackerjax was one of the most popular and successful bands in the North Jersey Club circuit. Now into the 90s, Beertz joined Benny and played for several years with the band Scarlet. He later, along with Debo and Bobby K, formed the "Last Kall Band" and has been playing the North Jersey club scene ever since.
The co-founder of "Last Kall", from childhood always loved music and dance. That love, after a stint in the military at age 23, urged him to pick up the bass guitar...He took several lessons from Ernie Swanson, leader of the "Crescents", who after two years, asked Debo to join the band. They went on to become one of the premier nite club bands of the 70's...The 80's were no different. He reunited with fellow Crescent, saxophonist Bob Annette, and his "Funn Band" drummer Bobby K and guitarist Johnny Beertz to form the group "Kracker Jax", who became the hardest working popular band of the 80's...The 90's brought new challenges. He was asked to join an already established band to be front man and lead singer; Hence the birth of the new "JokersWild Band"...The next decade brought Debo back to his former band mates, Beertz and Bobby K to form the "Last Kall Band". And now with Benny in the band, the cycle of changing musicians... continue.
Decade after decade his smooth and fat sound on bass, his lead vocals from artists: Smokey Robinson, Stylistics, to Temptations, Wilson Pickett, Rod Stewart, to the Boss-his back up vocal and his crazy humor- helps make "Last Kall", besides a great dance & party band, a complete and enjoyable evening. Debo asks,-"Who loves ya?".
