Steve Parish, a longtime member of the Grateful Dead family who worked on the band’s crew starting with his first concert in the summer of 1969, will take part in a Reddit Ask Me Anything (AMA) fan Q&A session this evening.

The session will take place on the Grateful Dead subreddit and is expected to last from 4pm PT to 6pm PT.

The subreddit has hosted a number of these AMAs in the past few months, including Q&As with Wavy Gravy, Dead publicist Dennis McNally, Grahame Lesh, Donna Jean Godchaux and more.
