Rare interference

I was playing one of those albums you only visit once every 20 years and noticed an interesting effect - something I hadn't noticed before (or consciously registered) on an album that Hawkwind fans will recognise - Robert Calvert's "Captain Lockheed and the Starfighters".

During the silences on the first B side track I could hear irritating buzzing coming from the noise floor. After a moment it dawned on me that I was hearing the high intensity engine revving noises from the WWII aircraft during the introduction on side A. The stylus was reading over-print through the disc.

May be one of the consequences of using a line contact stylus.
Tape enthusiasts are accustomed to hearing this type of effect from magnetic leeching, and pre-echo is common but this was slightly unusual.
Anyone experienced this?
Is that even possible? To hear stuff on the other side of the record? I'm not saying that its impossible, but it does seem far fetched.
