The father-son always look adorable when they work together. Be it their amusing act in "Kajraare" or serious performance in 'Paa' - audience is treated with good entertainment when they are on one stage. But this time, we tell you, they didn't share the screen space instead shared the mike!

For their forthcoming AB Corp's production 'Bbuddah - Hoga Terra Baap', Amitabh Bachchan has sung a special track along with beta Abhishek. The peppy track was said to have recorded quite recently and sharing the titbit, Big B quoted on his micro-blogging site - "At home and working out new promo for 'Bbuddah' ... this one with Abhishek and me singing... cool and rocking!!!"

Abhishek showed his singing talent in 'Bluffmaster' by singing the hip-hop number "Right Here Right Now". Later in 'Dum Maaro Dum' he again grabbed attention with "Thayn Thayn". Hmmm, Jr. B is proving to be an all-rounder...

Sources who heard the papa-beta's song from 'Bbuddah' revealed that Abhishek has done a fabulous job. While he has rendered his voice only for a stanza, the rest of the song is sung by Amitabh. However, Abhishek's stanza is considered as the highlight and his voice is said to suit his dad perfectly.
