Aaron Lefkove would most like to be remembered as the guy who coined the phrase "Summer of Megadeth."

You left out SATAN HIMSELF.
But He flows through all the Work of the Masters, and would thus be redundant.
And Tommy Saxondale
3:20 post? YEESH.
(Also you should all go to summerofmegadeth.tumblr.com and REFRESH CONSTANTLY, RIGHT THE FUCK NOW.)
Is that yours Matt?
Nevermind, I just discovered reading.
I'm not just a member, I'm also a contributor. (?) Also this is a thing that I've been known to do.
Hah, I think I followed you soon after I made a tumblr, but I know nothing about comics and shamefully unfollowed one day befuddled. But I didn't know it was you!
Ian Gillan hit on me in a crummy bar on the Upper West Side in 2005. I don't get hit on much, so it was weird to begin with. I thought at the time that "I'm the lead singer of Deep Purple" was just a really poor chat-up line. Googled him the next day and it was actually him, though.
I lit Tony Iommi's cigarette for him in the Tenerife Airport, in the Canary Islands. I didn't even know who he was at the time - I was 16 and into hardcore.
Then we get to Johannesburg and the airport is full of Sabbath fans - one guy asked me, 'hey, did you see Bleck Sebbeth on thet plyne'?
They were going down to play Sun City.
ouch.
Black and Blue, baby...1980.
Ronnie James Dio is on my short list for guys you don't want to be standing next to at the bar when the lights go on at 5AM. In 8 inch boots I think he came up to about my nipple.
According to Wikipedia: "His parents raised him in the Roman Catholic church, an experience he found unsatisfactory." ZOMG! Really!?!?!?! I would have never known!!!
That's for sure. Forget ex-Elf, I think he might be an *actual* Elf.
RONNIE JAMES DIO IS NOT DEAD!!! http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=140115
Bev Bevan has always been on my "best rock names of all time" list.
You're making a career of evil.
They're going to call you out, you know, for referring to a different band.
Yes, darling, I know it, but let's see who does. In every dreamhome, a heartache, etcs., you know.
It's okay, because that is one of the greatest songs ever written. We may have to do a series of BÖC posts now.
So why'd they go through so many people? Did they all, like, choke to death on someone else's vomit, or what?
I am learning to play 'Solitude,' today.
Three days after this post, Ronnie James Dio drops dead.
COINCIDENCE? I THINK NOT.
