Now, there is a song called Sausage Beans and Chips by the cartoon, hard-core, early eighties punk band (actually not a proper band, but that's another story) Chaotic Dischord, but this is a different song to the Welsh classic Sosej Bîns a Chips by the band Rocyn.
I won't post both the songs here for comparison, because the Chaotic Discord song contains some very, very bad language indeed, but here's the Rocyn song.
Unfortunately I don't know where to find a transcription of the lyrics. Sorry!
Rocyn, by the way is a Pembrokeshire word for boy. Crwtyn is the word you'll hear slightly further east.
