To anybody looking to check whether or not TC&TYR have still got the goods, then let me tell you: yes.
To be fair and honest, I actually went to see the opening act, Bricklin. As I found out during the show, Tommy himself reached out to Bricklin and asked if they wanted to pull off TWO reunions from 1986 in one night. Thank God they agreed; the lead singer even flew in from Paris. Bricklin is still as "rad" as they ever were (although only the drummer still has that hair)... but you're probably waiting to hear about the Rumblers.
For a band that I'd never listened to, I was really impressed - and this may sound weird to anybody who remembers them from way back when, owned the cassette, wore the shirt and saw them five times in one year. To me, it was a brand new band who never existed before that night, and I bought their CD anyway. Tommy's got great energy, he can still shred, he can work the crowd (at one point he was playing on a table in the middle of the audience... and took his pants off). None of the guys have lost their touch. Once or twice, somebody would make a little gaff, and Tommy would just yell, "AHH, SH*T!" into the mic, which more than makes up for it in my opinion.
Therefore, in conclusion, if you're in Philly the next time they decide to get together and do it again, you should totally go. Spare no expense. Tonight's the night!
