The Re-Echoes were a Baltimore group that featured guest lead singers.
For the above 1964 show, Brenda Jones was filling that spot .....

I came across another club ad from 1964 for a Re-Echoes show for which they had a different lead singer ......

I had a strong idea who Kenny was ..... so I asked Kenny Hamber if the lead singer on this show was indeed him & he confirmed that it was.
