Having relatives in the Osaka region, I can vouch for the observation that many Japanese in other areas have made about the folks from that area. They can be very loud and boisterous...perfect for the most commerce-happy area in the country. The above video features the 70s comedic duo Senri and Mari Unabara（海原千里・万里）, a sister act nattering away in the Osaka dialect at warp speed. The younger Senri on the right was actually born as Emiko Kaminuma（上沼恵美子）, and although the duo broke up in that same decade, Kaminuma returned to the spotlight some time afterward under her real name and has remained as one of the most venerable tarento and forces of nature on TV.
One of the things that I hadn't known about the duo was that they actually sang a few songs publicly as well. Among the four singles that were released by Senri and Mari Unabara was "Osaka Rhapsody" that came out in February 1976. I heard this today being sung on "Nodo Jiman"（のど自慢）so I decided to write about it. I was surprised to hear that this was a song that came out in the mid-70s since the intro sounds like the jaunty beginning to a wartime tune. However, the melody by Kosho Inomata（猪俣公章）then quickly simmers down to what seems like a travelogue through traditional streets...shopping here, nibbling on a few goodies there.
The lyrics by Michio Yamagami（山上路夫）have two young lovers making a whirlwind tour around the famous spots of Osaka such as Dotombori and Midosuji. Methinks that knowing the gregarious Osakans, the lovers would be totally exhausted by the time their hosts finally let them go for the night. Still, the couple simply cannot deny the food. And I cannot deny that the sisters sound quite polished behind the mike as singers instead of mere comediennes.
"Osaka Rhapsody" was the one big hit for the Unabaras as it sold 400,000 records and ended up as the 95th-ranked single for 1976. I'm not sure what her sister is up to now but I'm sure the former Senri-turned-Emiko would be more than up to sing the song if asked.
