Lataji recently completed 80 years of age and may God bestow her with more years and a melodious voice. We would love to hear her sing more like "Havaa mein udta jaaye, mera laal dupatta malmal" or "Dil hoom hoom kare, ghabraye". She has done 30000 songs in her illustrious career.
Out of curiosity, I browsed for SPB's records. From http://www.spbindia.com/AwardsAchievements.aspx , I found the following:
Has recorded over 36,000 songs in a span of 35 years, which include film songs and devotional numbers recorded by various recording companies of the country. It's a world record which will be soon entering into the Guinness Book of World Records.
Has recorded 17 songs in Kannada for the composer Upendra Kumar in Bangalore from 9.00 a.m. to 9.00 p.m. on February 8, 1981 which is a record.
Has recorded 19 songs in Tamil in a day, and 16 songs in Hindi in a day, which is a notable achievement.
