Two things, one for you, one for me (which is also for you):
1) I've been asked by several folks for Haggadahpalooza playlists, to practice for the seder. Firstly, I'm flattered. That's awesome. Secondly, I got you covered! On the book page, I've got Spotify and YouTube playlists that contain all the songs I've parodied. Enjoy!
2) I've now received 7 "Fan Covers" of the 56 songs I've parodied, and included them on the book page as well. Only 49 to go! Take your song pick, record your performance, send it to me, and I'll splash it all over Social Media, plus include it here on the book site. Thanks bunches! Keep them coming!
