I don't know if you can say which '60s garage tune is the best. But '60s garage is definitely the best music ever created. That's not an opinion, it's a clear fact

. As much as I like Chuck Berry.
5 of the best (of the best)
Adrian Lloyd - "Lorna"
13th Floor Elevators - "You're Gonna Miss Me"
The Chob - "We're Pretty Quick"
The Kinks - "All Day And All Of The Night"
The Tremors - "Wondering Why"
Also - ? & The Mysterians, The Blues Magoos, The Music Machine, The Sonics, The Easybeats and The Electric Prunes deserve every ounce of respect they earned. Lately I'd even have to include Love in that list.
But for me, the last tune left standing would have to be The Elevators. It's got everything - chilling screams, the coolest riff ever, the best bridge ever, unique instrumentation, the best vocal ever, brilliant sound quality and production, great lyrics.
