I was kind of surprised to read under the 'Tour Bus' tab for 1970 that Grace was pregnant and "unable to make live appearances" in October. I have to assume that refers only to some live appearances because she was fine on October 11, when Airplane played at Kent State's homecoming weekend. It was my first honest-to-God rock concert and I will never forget it. Sha Na Na (another Woodstock veteran act) opened. While I saw Sha Na Na several more times, this was the only time I ever saw Airplane perform live.
