Philosophy: Is Ok to sing Radhe Radhe during the bhajan?

do you mean to sing it as bhajan or to sing it whilst others are singing another song

I like it

I love it when someone calls out like that it seems to add the the mood

I haven't head or read anything against the practice and Radhe Radhe would seem appropriate content to exclaim

others?

can he call out Radhe Madhava instead

or Krishna Radhe

Morning Walk, April 8, 1975, Mäyäpur

Jayädvaita: Just like sometimes we'll hear our men. They'll be chanting... Like yesterday I heard that someone was chanting, "Nitäi-Gaura, Nitäi-Gaura, Nitäi-Nitäi-Gaura." Like that, I'll hear different mantras. Someone is chanting: "Rädhe, Rädhe, Rädhe, Rädhe," like that, at kértana.
Prabhupäda: Well, that is not done by the äcäryas. But there is no harm chanting "Rädhe." But sometimes it is degraded to make something new, invention. Therefore better to stick to "Hare Kåñëa" and to "Çré-Kåñëa Caitanya Prabhupäda-Nityänanda." Otherwise... Just like the sahajiyäs, they have invented: "Nitäi-Gaura Rädhe Çyäma, Hare Kåñëa Hare Räma." These things will come gradually. But they are not approved. They are called chara kértana (?), means "concocted kértana." But there is no harm chanting "Rädhe, Nitäi-Gaura." So better stick to this Païca-tattva, and mahä-mantra.

Mahanidhi Swami, Gaudiya Vaisnava Samadhis in Vrndavana, 7 (Sri Gaura Kishora dasa Babaji Maharaja):

Sitting in seclusion, he chanted 200,000 names of Krishna every day (128 rounds of japa). He felt painful separation from Radha-Govinda and cried profusely. As he wandered through the dvadasa vana (12 forests) of Vraja, he would loudly chant the holy names in a deep voice full of lamentation. He would also relish the following bhajan:

kothay go prema-mayi radhe radhe!
radhe radhe go jaya radhe radhe!
dekha diya prana rakho radhe radhe!
tomar kangal tomay dake radhe radhe!
radhe vrndavana-vilasini radhe radhe!
radhe kanu-mano-mohini radhe radhe!
radhe astha-sakhir siromani radhe radhe!
radhe vrsabhanu-nandini radhe radhe!
“O Radhe Radhe! Where are You, O Goddess of ecstatic love? O Radhe Radhe! All glories to You, O Radhe Radhe!
O Radhe Radhe! Please show Yourself to me and thereby maintain my life. Your most despicable fallen servant calls out to You, O Radhe Radhe!
O Radhe! Oh artful enjoyer of Vrndavana. O Radhe Radhe! O Radhe! Oh enchantress of Kanu's (Krishna) mind. O Radhe Radhe!
O Radhe! Oh crest jewel of Your eight main girlfriends. O Radhe Radhe! O Radhe! Oh delightful daughter of Maharaja Vrsabhanu. O Radhe Radhe!”


Bhaktivinoda Thakura, Gitamala 5.5.4:

radhe radhe boli', murali dakibe,
madiya iswari nama
suniya camaki', uthibe e dasi,
kemon koribe prana

The low, deep sound of His long murali flute will call out, "Radhe. . . Radhe. . ."—the very name of my own worshipable Queen! Startled with wonder by hearing such a sound, this maidservant will jump up in great haste with an extremely anxious heart, not knowing what to do next."
