note by teejo:
although there's no evidence for it, i think the old folks don shows us above are eric drew feldman's parents. because eric was a member of the magic band in the year the drawing was made, and beefheart was very taken with them, as he confessed in the interview where's the captain?:

i did enjoy playing with eric feldman, though. he's really nice and his folks are the most incredible people i've ever met in my life. his mother and father used to come see the music and actually really dig it. can you imagine that?

they lived in a nice house in the san fernando valley near this cigar store called the tinderbox, and he - his name was harold - had a t-bird and it looked good. he dressed really nice and he'd sit there, with liz, and wait for us to go on. they weren't there just to see their son, they wanted to hear some blow. one time i said to him: 'oh, you're here to see eric', and he replied in this real serious way: 'watch it'. that was his way of saying: 'i'm here to see the whole thing'.
