So, my nephew is out (I don't know how cardiac surgeons can stand it, these things go on for so long) and the surgery went well. Great thanks to God and to you all for praying and for your interest in, and concern for, this little fellow. His recovery may be slow, and still requires prayer, but the worst is now over. Apparently his VSD was huge and his aortic arch was tight, so he is not going to know why life is so easy when he recovers.
In thanks, here is a song. It's a dodgy live recording, but I like it. As it says on the youtube "The song, which was featured in the 1995 family film "Babe," adapts the main theme of one of the movements from Symphony No. 3 in C minor, Op. 78, by Camille Saint-Saëns". But here it is played very nicely on guitar.
