My very best mate from school was in the choir with me and anything musical, anything at all, that a pair of teenaged schoolboys could do we did together.
We sang the Beach Boys and Jan & Dean and Simon & Garfunkel and the Everly Brothers as we walked to school, all of it in perfect harmony. We learned to play honky tonk piano duets and swopped guitar chords we'd discovered. The first-ever recording of me playing rock music was a duet with the two us thrashing out Caroline by Status Quo on a pair of cheap Spanish guitars.
He went to university and studied music while I got an office job in London. 30 years later I took up bass so he came round for a jam on guitar. Even as a newbie on bass who hadn't touched a musical instrument in over two decades, I could tell that he wasn't great.
His 60th was earlier this year. He'd joined a band and been playing with them for two years, and the band was going to play at his party. Their first set was dreadful and he was comfortably the weakest member of the band. Their second set was indescribably bad; I've routinely taken part in jam sessions where none of the musicians on stage have even met before which sounded better than this.
When they finished playing, our chief interest was in finding a way of leaving fast enough that we could dodge the "how did we sound?" question.
In answer to the OP, no, I've never done anything like he describes.
