I've got a friend called Peter

Bunny, Yes they were! very good disciples! would've liked to meet them!! ( ohhh! how i wish time travel was real!!)

Player #97184361, and,/or, Peter and Paul, were also disciples of Jesus Christ.

I am wondering why is the names and connections to (Peter and Paul ) not explained here. There isn’t even a hint about the names. Peter and Paul and (Mary) was an American folk’s singing group in the 60’s & 70’s. ! ! !
