The four songs listed as 3/26/68 may belong to 3/29/68 (according to notes on Dick's DAT).
I'm not sure who came up with the 3/26/68 date. The DAT says: 1) 3/29/68 - Carousel Ballroom I THINK!!! (The "I Think" comment is in red ink) Schoolgirl Death Don't Have No Mercy Sitting On top Of The world Dark Star 2) 3/29/68 - Carousel Ballroom Morning Dew Lovelight -> That's It For The Other One -> New Potato Caboose -> Born Cross Eyed (cut at start)
