Heinlein in the 1960s
This show has been flagged as Clean by the host.
The 1960s were when Heinlein produced some of his most famous works. And they started to bring him fame outside the Science Fiction community, which was most unusual.
Heinlein in the 1960s
Heinlein had interests that he tended to keep hidden in the early years while he was establishing himself as a writer, particularly as he was feeding the lucrative Juvenile market. These included things like sex, nudism, and unusual political and religious views. But when Scribners rejected Starship Troopers he not only...
HPR4739: Happy by shower # 3
This show has been flagged as Explicit by the host.
We focused, until now, on things external as examples. Let’s proceed to internal. Before, I want to note that any of these is a formula. It’s not like we can repeat a past experience we ourselves or someone lived, and feel the same thing. It’s not a guarantee, and not even the idea in sharing. It’s only this: to share and to provoke reflection.
I was abused as a child. Hard as it is, and unerasarable, also hard was to tell someone...

HPR4734: HPR Beer Garden 20 - TuxJam Half-cut Special
This show has been flagged as Clean by the host.
The usual trio of Dave , Kevie and Paul meet up for the first time in person and are joined by Al , Andrew , Joe and Rainy. The meet up was for the TuxJam Half-cut live event in Manchester. Rather than the usual style of show this is a (mostly) unedited recording of the beers that we are trying and general yarns around the table. We were interrupted by a yelling numpty, a middle-aged boy racer and a tram (these were edited out), but otherwise the recording is pretty...
