After his return, Reinhardt re-immersed himself in Romani life, finding it difficult to adjust to the postwar world. He sometimes showed up for scheduled concerts without a guitar or amplifier, or wandered off to the park or beach. On a few occasions he refused to get out of bed. Reinhardt developed a reputation among his band, fans, and managers as extremely unreliable. He skipped sold-out concerts to "walk to the beach" or "smell the dew." During this period he continued to attend the R-26 artistic salon in Montmartre, improvising with his devoted collaborator, Stéphane Grappelli.
