House Cricket singing in Gorseinon

At 22:30 just as I was jumping in the car I was amazed to hear a House Cricket singing in the front garden. The temperature according to the car was 12.C.  15 minutes later when I returned the temperature had dropped a couple of degrees and the singing had stopped, but another check 5 minutes later and it was singing once more albeit just for less than a minute.  A quick check on line confirmed the song was House Cricket (Acheta domesticus) rather than Tropical House Cricket (Gryllodes sigillatus). Hopefully it will be singing again tomorrow and I'll get a recording...

Has anyone else heard House Crickets - I suspect keepers of spiders and reptiles are probably the source of our cricket?
