Have you ever seen the rain?

Heard this Creedence Clearwater Revival song, from from 1970 album "Pendulum", on the Fantasy label, in two different formats, simultaneously, last weekend:

1. Album version, playing over speakers, at Marini’s Westside, 332 Ingalls St., Santa Cruz
2. Acoustic guitarist, playing an amplified cover version, on the outdoor patio of MJA Vineyards Westside Tasting Room & Cellar, 328-A Ingalls Street Santa Cruz

Coincidence : ) Different tempo, key, and so forth.
