The best part? About half way through the song, you can faintly here someone say, "How much were those tickets?" Actually, I made that up. But still worth a listen to. Link & technical analysis provided by RW370...
So what happens when you’re Van Halen, the last song in your set list is the million-seller "Jump" with its synthesizer-keyboard opening…and the recording you’re using to play back the synth is accidentally run at 48K instead of 44.1K?
...Eddie tries to transpose on the fly and match the wildly fucked up keyboards but the great thing there is the difference in pitch is non-musical - about 1.5 semitones sharp. So there’s no frets he can choose to fix the problem!
