According to Sound on Sound, a Hohner Electra Piano was played on the Beatles' track "Come Together":

The instrument was used on some famous tracks: the Beatles’ "Come Together" has a brief Electra solo, and Led Zeppelin used one on number of tracks including "Stairway To Heaven."

According to The Beatles Bible, it was Paul who played the electric piano solo on this track.

The Keyboards of Led Zeppelin & John Paul Jones website covers John Paul Jones's use of the Hohner Electra Piano:

Jones preferred recording with the Hohner instead of the popular Rhodes and Wurlitzer pianos, as he liked its stiff keyboard action better. John Paul Jones didn't use the ElectraPiano live; only in the studio. This is because its wooden casing was more like home furniture, and was not too portable. It's sound was not clear live. "It didn't really cut through. Plus, it wasn't really built for road work. It was the sort of thing you'd have in your front room. I think that's what it was designed for," said Jones.

"Stairway To Heaven" is Led Zeppelin's most famous track, and the Hohner piano is played in a supporting role beginning at 2:14. Jones recalls playing directly into the console and using the Hohner for the piano chords with left hand bass. The part is very subtle, a supportive texture underneath the guitar tracks that follows the chord progression.

Following "Stairway To Heaven" on Zeppelin's fourth album is "Misty Mountain Hop," a bouncing heavy rock song that is based around a strong syncopated ElectraPiano riff. The riff continues throughout the song and is heavier sounding than the "Stairway To Heaven" piano, as it was recorded through its amp and speaker, not directly to the console.

Led Zeppelin's most obvious "keyboard" song comes from the Houses of the Holy album. Beginning with a long electric piano instrumental, "No Quarter" was Jones's featured solo section in the live show for many years. The Hohner is processed through an EMS VCS3 synthesizer to create a 'wobbly' sound. In concert, Jones extended the song with lengthy improvisations and duets with Jimmy Page on guitar.

"Down By The Seaside" is another Hohner ElectraPiano song, with Jones playing a traditional country-pop piano arrangement.

This Hohner ad reads “Gordon Beck plays the Hohner Electra-piano.”

Sound on Sound’s piece on inventor Ernst Zacharias claimed Beck performed the most definitive Electra Piano recording:

The definitive Electra Piano recording features the British jazz pianist Gordon Beck playing a long solo introduction to ‘Ariadne’ on the Nucleus album Labyrinth from 1973. Here, we encounter in full the gorgeous harp-like quality of the Electra.

The article later had this to say about Beck’s deal with Hohner:

One story we heard from a student of Gordon Beck was that Beck had an endorsement from Hohner to use the Electra Piano. He devised his own portable chopped version of the Electra, which he claimed Hohner copied for the T. When he was presented with the factory version he was so disgusted with the way his design had been adapted that he gave up playing Hohner instruments and from then on used Rhodes pianos instead.
