Warm up your brain cells

Morning Folks! No book reviews today, but I do need your help with a couple of tricky clues for a competition that I’m trying to enter.

In this competition festive song titles and their artists have been muddle up. The letters need to be rearranged, but all the vowels are also missing.

For example; RHCTHTMSWS is WHITE CHRISTMAS and RGBBSYNC is BING CROSBY.

I need help with;

GSHDHBCRR

BCDLNJL

GVPMLSRNCMCTLN

Two of them will be linked ie song and artist, the other will be on its own. I’ll be grateful of any help at all.

Cheers
