Keane, swayed by the Little Richard connection, went to see Valenzuela play a Saturday morning matinée at a movie theater in San Fernando.
Impressed by the performance, he invited Ritchie to audition at his home in the Silver Lake area of Los Angeles, where he had a small recording studio in his basement.
When he was sixteen years old, he was invited to join a local band named The Silhouettes as a guitarist.
"Donna" was one track (although there are two other preliminary versions of the song, both available on ``The Lost Tapes), and the other was an instrumental entitled "Ritchie`s Blues".
After several songwriting and demo recording sessions with Keane in his basement studio, Keane decided that Ritchie was ready to enter the studio with a full band backing him.
A sheer hemline and subtle peplum added interesting focal points to otherwise completely beaded frock.

The recording equipment comprised an early portable tape recorder — a two-track Ampex 6012 — and a pair of Telefunken U-87 condenser microphones.
After this first `audition`, Keane decided to sign Ritchie to Del-Fi, and a contract was prepared and signed on May 27, 1958.
The demos were mostly just Ritchie singing and playing guitar. These original demos can be heard on the Del-Fi album Ritchie Valens — The Lost Tapes.
As well as the aforementioned demos, two of the tracks laid down in Keane`s studio were taken to Gold Star and had additional instruments dubbed over to create full-band recordings.
At his appearances he often improvised new lyrics and added new riffs to popular songs while he was playing.
This is an aspect of his music that is not heard in his commercial studio recordings.
Amongst the musicians were Rene Hall and Earl Palmer.
