HOW EARLY

Haven't been to 9:30 since I saw Cracker in 2000 thinking I wouldn't get the chance to go again (5 months pregnant at the time)  Going to see Social D on Tues.  Are there long lines for Will Call and what time should we get there?  Bought parking.  Thanks!
There tend to be long lines at sold out shows.  How early to get here?  Not sure,  but I hear great things about both of the openers so 7:30 might be a good time to get here.
