"velludai porthiya melli dhegam

"1948-il 52 padangal velivantha pothu avatril 48 padangalukku

There are Vairamuthu's words.

Muruthakaasi's native is Melakudikkaadu, a town near Kumbakonam.
Was born in a farmer's family.
Initially he was writing for many dramas including A.K.Velan's 
"Suraavali" and Kalaignar's "Ore muththam". Like Ka.Mu.Sheriff,
he was also introduced by Modern Theatres in "maayaavathi".
The song was "Adichathu yogam" under G. Ramanathan's music.

He once wrote a song "kundusatti vayirazhagaa milagaa mookkazhagaa
nandukaal nadayazhagaa paalaivana thalaiyazhagaa" which indirectly
is a satire on G. Ramanathan.
After his movie "Alli petra pillai" was a disaster, it seems he wrote
the song "nenachathu onnu nadanthathu onnu".

He has been writing for more than 37 years now. 
Some of his songs are

aermunaikku ner inge ethuvume ille - pillai kaniyamuthu
manappaarai maadu katti - makkalai petra makaraasi
aadura maattai aadi karakkanum - arivaali
neela vanna kannaa vaadaa - mangayar thilagam
varuven naan unathu - mallikaa
otrumayaai vaazhvathaale - bhaagapirivinai
ninainthu ninainthu nenjam - sathaaram
konji konji pesi - kaithi kannaayiram 
vasantha mullai polevanthu - saarangathaaraa
mullai malar mele - uthama puthiran
ennaivittu Odi poga mudiyumaa - kumudham
en vaazhvil puthupaadhai kanden - thanga pathumai
vaaraai nee vaaraai - manthiri kumaari
ulavum thendral kaatrinile - (-do-)
aannaakka antha madam - aayiram roopaai (Apparently, kavingar was
searching for pallavi while writing this song. What KVM jokingly
said that time, was finally used for the pallavi.)
thirunaadu thannil thiruvodu aenthi - kanavu (appreciated by Anna)
maruthamalai maamaniye - dheivam (got state govt award)
kadavul enum muthalaali - Vivasaayi

"antha kaalathil ellaa kavingargalidamum otrumai irunthathu.
ippothu appadi illai. comedy paadalgal endraal thanjai
raamayya thaas. uvamai sirappu endraal suratha. janaranjagamaana
paadalukku udumalai. samuthaaya puratchi paadal endraal
pattukkottai. kaathal endraal kannadhaasan", are his views
on other lyricists.

He never wrote for Ilayaraja due to some ego struggle. He once
commented "Indru cinema ulagam vyaabaara ulagamaaga maari vittathu.
avaravargalukku thevayaanavargalai avaravargal anugugiraargal.
murattu kuthirai(Ilayaraja) meethu savaari seyya mudiyaathavargal
avaravargalukku aetra kuthirayin meethu savaari seithu kollalaam.
enakku thamizh mukkiyam. enave naan konjam othungi irukkiren".

Udumalai naaraayana kavi was apparently his maanaseeka guru. Kudanthai
vaani vilaasa sabha confered on him the title "Thirai kavithilagam".
Kalaignar comments "Muruthakaasiyin paadalgal inikkum endru
solvathu, sarkkarai inikkum endru solvathai pondrathu".
