For musicians, the opening chord of The Beatles' "A Hard Day's Night" has been something of a puzzle. It's a distinctive chord but it's not clear exactly how many instruments are playing, which instrument is playing what, etc. Check out this audio of Randy Bachman on the CBC talking about getting to Abbey Road studio and finding out exactly what it is. Pretty thrilling for anyone who's ever wondered about it! You can hear the genuine excitement in Randy's voice!
