I don't know of a site offhand, but A couple points to note:
It depends on when in June you plan to go. The first week or so in June is not summer season yet, so the close times and what is presented nightly is different than the typical summer hours, which generally start anywhere from June 6th - 13th.
Mickey's Jammin Jungle Parade is almost always at 4pm daily.
SpectroMagic tends to be either two hours or three hours before the MK closes and then a second showing 1 hour before the MK closes. In other words if the park closes as midnight, then there is usually SpectroMagic at 9pm and 11pm with Wishes (or the fireworks show) at 10pm. In June, it gets dark very late, so don't expect any night time stuff before 8:00pm. If SpectroMagic is not showing at all, then they usually do Wishes at around 9pm.
Disney is notorious for randomly swapping showtimes and even cancelling performances, so it may be difficult to guesstimate.
. The suggestions and the website are very helpful. I will definitely keep in mind that this is only a guesstimate and Disney will mostly likely change it. ShadowWind - we are going right when the onslot begins in June (no real choice secondary to school schedules) but we will have 8 days for park touring, so by doing some planning I am hoping we will be able to see a lot, not everything, but a lot. We will be there from June 11-20, 2005. What I am really excited about is this trip is a surprise for my 3 godchildren 12, 10 & 5 and I can't wait. They have never been to ANY Disney park and they would never be able to go without monetary help, so my husband and I are taking them and my best friend, their Mom. I am the big Disney fan in their lives, so everytime I am around they bombard me with questions about Disney. I can't wait to tell them (their Mom knows) but we aren't going to tell them until a few days before we go. They are going to be so excited 
. Also 2 of the kids will have their birthdays while we are there. Which is even better. Can't wait
