The only guy I remember that did his show from his basement was Ken Mayer who wrote the "Night Mayer" entertainment features in the Boston Herald. I don't recall that he used "L'il Darlin"...his show was on Sun night at midnight for two hours and he played the same 20 or so comedy LPs over and over between one-sided phone calls.(You'd hear his side of the call, but not the person calling in.)
If memory serves me, he could have been simulcast on WUNR 1600 and WBOS-FM.
There was a guy who did a daily oldies show weekday afternoons on WUNR named Jack Diamond who played "million dollar mindstickers" for his "kimosabes". I don't recall if that program was also on WBOS.
